Can't install on Win7 at work

I installed Station successfully without any problems on Manjaro (my main system at home) last night and wanted to install it also at work on my Windows 7 laptop. I downloaded browserX-Setup-1.43.2.exe and run it. It ended with an error. Here is the log:

Update: Even admin couldn’t install Station, the same issue appears.

Has Station even supports Windows7? It tries to write to some strange locations to which has no rights to access, even with Admin access.

Newest browserX-Setup-1.44.1 still shows the same issue.

   w System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

Why does it try to write into Slack folder?

I think I know why I had the issue. The installed system is 32bit and the app is 64bit so it simply won’t work.
I assume there is no 32bit version available?
