Bug 5163

[EA Durbin]

It appears to me according to this log section that the bug is actually in 
kernel32.CompareStringA, though I could be wrong.  It starts out comparing 
the strings of files it is looking for in the cabinet file with 
kernel32.CompareString and unsuccesfully matching, then it appears to be 
matching the first couple of letters in the string and then continuing on 
before it actually finds the file it is looking for.

SC2R.SAM is matching scanost.exe
EXCHCSP.DLL_0001 is matching exchng.hlp

after it finds these false matches the installer continues on without 
actually matching the string it is looking for
