I've had a look and the installer is failing because of the result returned by :
0009:Call version.VerFindFileA(00000000,0040b4ec "JaTennis32.exe",0040e268
"c:\\Windows",00417bf4
"Z:\\var\\work\\crosovergames\\downloads\\bugs\\OpenFile
regression\\",004179e4,7babfe0c,00417af0,7babfe10) ret=0040143d

VerFindFileA then goes on to call OpenFile, so I expect that the error is  VerFindFileA is
testing
the result of OpenFile against FALSE instead of using TRUE or HFILE_ERROR.

....
VerFindFileA is returing 2 (VFF_FILEINUSE) if OpenFile returns HFILE_ERROR, but it's returning 0
if OpenFile returns FALSE.

I think it's a good idea to revert OpenFile and fix VerFindFileA.
