LibreOffice Tuesday T&T: Windows Installation Issues

According to our estimates, worldwide there are around 150 million LibreOffice users on Windows. And when we say worldwide we mean worldwide, as according to the origin of downloads we have users in every continent including Antarctica.

As a consequence, we get a large amount of questions related to LibreOffice on Windows. Many of these questions are about the installation process, because there are several issues which prevent the user to get the expected positive user experience. Unfortunately, the majority of these questions are related to Windows issues and not to LibreOffice issues.

When a issue is related to Windows, the Microsoft operating system will show a specific message, under the form of either an error number (for instance, “Error 1303”) or a specific sentence (for instance, “The program can’t start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer”).

Of course, over the years we have built a small knowledge base on the subject, and we have published the results on one page on the wiki, in the area of frequently asked questions: https://wiki.documentfoundation.org/Faq/General/General_Installation_Issues_(Windows). Another useful resource is the Ask LibreOffice website (https://ask.libreoffice.org/en/questions/), where users can search for a solution.

The best resources, though, are provided by Microsoft, and are all multilingual, and are the Microsoft Support website (https://support.microsoft.com/) and the Microsoft Community website (https://answers.microsoft.com/en-us). For instance, a search for “Error 1303” provides around 20 answers, with comments, on the Ask LibreOffice website, and hundreds or even thousands of answers on the two Microsoft websites.

LibreOffice is a hot target for the Google Season of Docs 2020

For the second year in a row, The Document Foundation has been accepted as an organization in the Google Season of Docs, a programme whose goals are to give technical writers an opportunity to participate in contributing to open source projects, and to give open source projects an opportunity to engage the technical writing community.

This year we offer a wide range of projects for technical writers, and we’re extending the reach by providing projects for e-learning, mathematical documentation and code-oriented documentation.

During the programme, technical writers will spend a few months working closely with the LibreOffice community, bringing their technical writing expertise to the project’s documentation, and at the same time learning about the open source project and new technologies. Similarly, LibreOffice documentation team members will work with the technical writers to improve the project’s documentation and processes.

LibreOffice is an advanced office suite covering many areas of knowledge, from maths and sciences, engineering, financials, editing, drawing, printing and more. LibreOffice is also an application that is used cross-industry – so it’s a very rich opportunity for technical writing.

Olivier Hallot, LibreOffice’s documentation coordinator, will lead the GSoD project, supported by Ilmari Lauhakangas and members of the LibreOffice documentation team.

All information about the Google Seasons of Docs is on the GSoD website. An outline of the project’s different steps is available on the GSoD timeline. The next deadline is June 8, as we we need to find interested technical writers to discuss our ideas, which are summarized on the following TDF wiki page. The list includes some of our project’s permanent challenges, but should not be limited to these items. Technical writers must read the technical writer page of the programme.

LibreOffice contributors who are interested in becoming a mentor for the GSoD project should get in touch with Olivier Hallot by sending him a message. We look forward to hearing from you!

Community Member Monday: Marco Marinello

Today we’re talking to Marco Marinello from the Italian LibreOffice community, who recently became a member of The Document Foundation, the non-profit entity behind LibreOffice…

Tell us a bit about yourself!

I live in Bolzano, which is a small city in the northernmost part of Italy. My main interests are robotics and computer technology. In my spare time I often enjoy going for a ride with the bike, which I use almost every day to get around. In the summer I spend my holidays sailing with my family and some friends.

Why did you decide to become a member of TDF?

During SFScon – the Free Software Conference in Bolzano – I met Marina Latini, former Chairperson of the Board. We talked about the work I did on LibreOffice Online, and she encouraged me to send the application and become a member of TDF.

I share the values of TDF, and I love working on something that’s useful for everyone.

What exactly are you working on right now?

Mostly, I’m working on the documentation for LibreOffice Online, but I’m even submitting some changes. Documenting features that have already been implemented well is the first goal which I have set myself.

Anything else you plan to do in the future?

If I became more skilled in C++, I would like to get more involved with developing LibreOffice. I think a solid and compact group of members who really care about the product and the strategies is the strength of TDF.

Thanks to Marco for all his contributions! Everyone is welcome to join our friendly community, develop skills and meet new people. We look forward to meeting you!

Join the first Bug Hunting Session for LibreOffice 7.0!

LibreOffice 7.0 is being developed by our worldwide community, and is due to be released in early August 2020 – see the release notes describing the new features here. Of course, there’s still a lot more development to come, so more features will be added to that page in the coming months!

In order to find, report and triage bugs, the LibreOffice QA team is organizing the first Bug Hunting Session for LibreOffice 7.0 on Monday May 11, 2020. Tests will be performed on the first Alpha version, which will be available on the pre-releases server a few days before the event. Builds will be available for Linux (DEB and RPM), macOS and Windows, and can be installed and run in parallel along with the production version.

Mentors will be available from 07:00 UTC to 19:00 UTC for questions or help in the IRC channel #libreoffice-qa and the Telegram QA Channel. Of course, hunting bugs will be possible also on other days, as the builds of this particular Alpha release (LibreOffice 7.0.0 Alpha1) will be available until end of May. Check the Release Plan.

During the day there will be a dedicated session to test the ongoing work in the SKIA Graphics Engine integration from 14:00 and 16:00 UTC.

All details of the first bug hunting session are available on the wiki. LibreOffice is a volunteer-driven community project, so please help us to test – we appreciate it!

The New Getting Started Guide 6.4

The LibreOffice Documentation Team proudly announces the immediate availability of the LibreOffice Getting Started Guide 6.4, the introductory guide for the latest LibreOffice 6.4, aimed to the general public interested to quickly get familiar with the software.

The Guide was updated from the existing release 6.0 and includes an introductory documentation of the most common features of the free office suite and includes information on word processing, spreadsheets computing and charting, presentations, drawings, database management, equations and also macro programming. The update includes the changes in several components of the suite and new features introduced since release 6.0.

The Guide also introduces extensive information on the LibreOffice way of producing professional documents by using the rich set of formatting styles and correct document file format such as the Open Document Format. Needless to say, the Guide was edited, reviewed and assembled using LibreOffice 6.4.

The Getting Started 6.4 guide is the result of the collaborative work of Andrew Jensen, Claire Wood, Dan Lewis, Kees Kriek, Steve Fanning, Pulkit Krishna, Roman Kuznetsov and was reviewed and assembled by Jean Hollis Weber. A big thanks to them for all their work!

LibreOffice has extensive documentation in many languages, thanks to our worldwide community.

You can also get individual chapters via this page.

Everyone is welcome to join our documentation team! It’s a great way to build up experience in a large and well-known open source project, especially if you’re interested in a career in technical writing one day.

Annual Report 2019: LibreOffice in 2019

(Note: this is a section from The Document Foundation’s Annual Report 2019, which will be published in full in the coming weeks.)

In 2019, LibreOffice celebrated its ninth birthday. Two new major versions of the suite introduced a variety of new features, while minor releases helped to improve stability as well.

Throughout the year, several Bug Hunting Sessions were held in preparation for the new major releases. These typically took place on a single day between set times, so that experienced developers and QA engineers could help new volunteers to file and triage bugs via the IRC channels and mailing lists. The Bug Hunting Sessions for LibreOffice 6.3 were held on May 9 and July 8 – while those for LibreOffice 6.4 took place on October 15 and December 18.

LibreOffice 6.2

On February 7, LibreOffice 6.2 was officially released after six months of development. It was the first version to showcase the new (but optional) NotebookBar user interface as a non-experimental feature, making it available for all users. The NotebookBar is available in Tabbed, Grouped and Contextual flavors, each one with a different approach to the menu layout, and complements the traditional Toolbars and Sidebar. The Tabbed variant aims to provide a familiar interface for users coming from proprietary office suites and is supposed to be used primarily without the sidebar, while the Grouped one allows to access “first-level” functions with one click and “second-level” functions with a maximum of two clicks.

LibreOffice 6.2 also included tidied-up context menus, performance improvements for change tracking, multivariate regression analysis in Calc, and many extra features in LibreOffice Online. A video was produced to explain and demonstrate many of the new features in LibreOffice 6.2. This was linked to in the announcement, and embedded into various web news websites that covered the release. Here it is:

LibreOffice 6.3

Later in the year, on August 8, LibreOffice 6.3 was made available. Writer and Calc performance was improved by an order of magnitude based on documents provided by end users: text files with different bookmarks, tables and embedded fonts, large ODS/XLSX spreadsheets, and Calc files with VLOOKUP load and render more quickly. Saving Calc spreadsheets as XLS files was also made faster.

Meanwhile, the Tabbed Compact version of the NotebookBar user interface, introduced in LibreOffice 6.2, was made available for Writer, Calc, Impress and Draw. It leaves more space for user documents, spreadsheets and presentations on laptops with wide screens. In addition, the new Contextual Single UI was ready for Writer and Draw.

Export as PDF was improved with the support for the standard PDF/A-2 document format, which is required by several organizations for long term file storage. In addition, the design of editable PDF forms was simplified with the addition of the Form menu to Writer.

Finally, a redaction feature was added to remove or hide sensitive information such as personal data before exporting or sharing the file, to help companies or organisations to comply with regulations. As with the previous release, a video was created to demonstrate the new features:
