I have just tried the 2.3.4 installer on a clean 64-bit MS Windows 10
virtual machine and did not get any warnings or errors related to
missing DLLs.

The Xpra 2.x series switched to native builds thanks to MSYS2. This
doesn't use MSVC for building anything so I don't understand why you
would need the VC runtime.

Can you please create a ticket or post the information that would allow
us to fix this problem? (things like the full OS version and patch
level, installer filename, full error message, etc)

No fiddling should be necessary. For using a non-standard ssh port like
2222, simply use:
xpra attach ssh://HOST:2222/
