I'm not sure what your concern is
The first time I installed OBS, I had trouble as it turns out somehow I installed the 32-bit and 64-bit versions of OBS, and plug-ins got wonky (user error). With uninstall of both, then clean x64 install on Win10, it was fine. Now, where it can get tricky is 3rd party plug-ins, scripts, etc that may have their own requirements (Visual C++ , Python, etc)
have you checked out
