Cryptomator-1.4.0-beta2-x64.exe parallel installation with 1.3.4?

Hi there

I am running 1.3.4 on Win7.
May I install and run Cryptomator-1.4.0-beta2-x64.exe in parallel?
I would like to use my productive safe with 1.3.4 and creating in parallel a test safe with the beta.


I made the desired setup on a test machine - it did not work!
