I've tried to set a second Boxcryptor account for my wife on her Windows account (Windows 10). First I've tried to install Boxcryptor (with the last setup file : Boxcryptor_v2.39.1135_Setup.msi). When running the setup file, the only option I got was to remove Boxcryptor so I've quit the setup wizard. I've realized it was already installed through my personal Windows account in "C:\Program Files (x86)\Boxcryptor" as I've been using Boxcryptor without any problem for two weeks now in my personal Windows account.
So I run BoxCryptor, have started to login with the new account of my wife, but suddenly Boxcryptor quit. When I tried to restart it again, a Windows popup has appeared to tell me that the file that shortcut refers to has been deleted! I've checked in C:\Program Files (x86)\Boxcryptor, and the executable "Boxcryptor.exe" was missing but the other Boxcryptor files were there. Quite strange!
I've thought to virus symptoms but I am well protected with antivirus and I did not see any other executable deletions on my computer and the other programs work well.
I tried 2-3 times to uninstall Boxcryptor, restart my computer and reinstall it but the same problem occurs, whether in my personal Windows account or with the Windows account of my wife.
Thank you for your quick help.
