I had similar problems. Through trial and error I figured out that the location in the resulting .exe file for storage of the icon and file details is limited.
The icon I was using was too large and was overwriting the details resulting in a corrupted .exe. The solution was to use a smaller icon (16x16 32bit) and limit the length of the detail fields. I use the Perl module Win32::Exe to modify the file icon and details instead of a third party utility. I haven't done the research to figure out the size limitations. Now when I have a problem it is due to a detail field being too long so I shorten it till it works. If anyone on the list knows the exact size limits for the icon and detail fields please share the information. keith -- Keith R.
