Is it possible to install Libre Office on one computer simultaneous in the language versions English, Dutch and or Norwegian (w7)?

Hi

Parallel installations and SI-GUI were cited. SI-GUI is very good and I use it to download and test different versions of LibreOffice.

In this case the request is to use simultaneously the same version of LibreOffice with different interface languages. This is actually quite simple:

• Copy your user profile folder to another directory (e.g. below file:///C:/Test/LibreOffice)

• Create a batch file (just one line), here for windows 32 (adapt to your system):

  "C:\Program Files (x86)\LibreOffice 5\program\soffice.exe" -env:UserInstallation=file:///C:/Test/LibreOffice

Start the "other" session of LibreOffice with this batch. You can reset all parameters, including the interface language.

This is described in help.

When installing LibreOffice, you can choose which UI languages to install. Simply choose the ones you need. After setup, you can then switch UI languages under Tools > Options > Language Settings > Languages.

Installing release versions of LO using MSI installer does not allow to have several side-by-side versions of LO on one computer.

However, in the installer, you may choose to install several UI languages; and then you may select UI language in LO (Tools->Options->Language Settings->Languages). Restarting LO after the change gives you the required UI language. As this setting is saved in user profile, any user account of a computer may have own LO language.

If you need to have several language UIs open simultaneously, then you have to use parallel installations. The best way is using SI-GUI application available here. You may use it to install the same version of LO into different folders, and have different settings for each one, and start them in parallel.

Actually needing LibO with different UI languages (or generally with different user profiles) you might prefer LibreOfficePortable expanded to AnyFolder from the appropriate .paf.exe package from this download archive (many versions) or from this PortableApps page (recent version).
To allow for many instances running at the same time you only have to insert the line
SingleAppInstance=false in the [Launch] section of the .\App\AppInfo\Launcher\LibreOfficePortable.ini file accessible on the given relative path from the AnyFolder you chose in each case.
(Win file associations will be of no value anyhow under your premise.)
If you want to also install offline help for the different languages you may read this rather exhaustive guide. Sorry. It is a bit wordy.

(Editing:)
It is reported that the portable versions also work well on linux under Wine. They are 32-bit to date.

I would add to Mike Kaganski's answer that the SI-GUI depends on Microsoft's .NET being installed to the system. (The SI-GUI installer will automatically ask if you want to download and install .NET) If you don't have, and don't want, .NET on the system then it is possible to do a manual parallel install of LibreOffice.

The instructions on how to do a manual parallel install can be found here: Installing Several Versions of LibreOffice in Parallel. The instructions look a bit complicated but in practice it is easy to do.

In the parallel install instructions for Windows - under the heading User Configuration - only one option for where to store the User Data for the parallel install is given. However, several options are possible for editing the bootstrap.ini file - those other possibilities can be seen here under the heading bootstrap.ini: http://dev-builds.libreoffice.org/si-...

Also in the manual install instructions it is implied that the user should launch the parallel install LibreOffice only via soffice.exe. However, it is safe to directly launch whatever component of LibreOffice you want to use e.g. sdraw.exe, simpress.exe, swriter.exe etc. Whatever component you use LibreOffice will always read the bootstrap.ini file for where to read/write user data/settings.
