Can we install 2 different release on Windows ?

Aplogises, if the question seems silly...

I dot not operate on Windows  and my memories of this OS fade every day a bit more so I just want to have a confirmation. I would like to install on someone's PC running Windows 8 the last nightly build (from SourceForge) in addition to current 2.1.3 release.
1/ Is it possible ?
2/ Will it break anything on 2.1.3 version ? Libraries, etc...

Thanks.
Fabrice.

Certainly possible with PortableApps or LibreCADPortable_2.2.0-rc1.paf.exe.

The installer really needs a rework to do it properly - see https://github.com/LibreCAD/LibreCAD/issues/1148.

I have multiple installs of 2.1.3 as portable app, in several layouts, in parallel with the latest nightly build as normal install, without any problems.

Thank you.
