I'm afraid I can't reproduce the problem.  What I had to install on 32-bit 
Windows 8.1 was
Microsoft Visual C++ Redistributable (x86) - 14.0.23026

But if I uninstall this, Xpra and Xpra installers still work. (Doesn't matter if 
it's 2.3.4 before or after the OpenGL fix or 2.4 beta.)

The error I got was xxxx140.dll missing; I didn't record exactly the leading 
characters, but it's an error I've seen often enough to recognize that a C++ 
redistributable was needed.  Probably it  was MSVCP140.DLL.  Most machines will 
already have this either because some other application needed it and Windows 10 
probably includes it in the base OS.

The fiddling certainly had a large component of new user confusion. I recall 
playing with what I might call punctuation, i.e. slashes and colons. To attach 
to an existing connection rather than starting a new one, my bat file does 
pretty much what you specify.

start xpra attach ssh/%username%@%host%:%port%/%display%

I have never actually had a need for a non-default display; it just adds 
complication to my bat file.
