Detecting if a file is 32 or 64 bit

[numberofcode]

I need to check if a file (in this case an executable) of an installed program is 32 or 64 bit. Does installshield provide a method to do this? I was thinking something with GetFileInfo(), but it doesn't seem to provide any options of finding if the file is 32 or 64 bit.

Any ideas?
(this is for a basic msi project on a windows machine)


Thanks.

Detects only executable files. This API fails for dlls and other binaries.

prototype BOOL Kernel32.GetBinaryType(BYVAL STRING, BYREF LONG);

Worked perfectly.


Thanks.
