When I do something like this:

 Code:
if exist ("%programfiles%\Mozilla Firefox\") = 1
then do whatever
Endif


This will detect c:\program files\mozilla Firefox\ in Windows 7 32 bit, but does not work in Windows 7 64 bit. I have to change %programfiles% to c:\program files.

Yet when I run set in cmd on Windows 7 64 bit, the %programfiles% variable definitely points to c:\program files.

So I assume that this is some bug in Kixtart. Tried with versions 4.66 and 4.67
