Gaming 32-bit program having issues on 64-bit

[jumpman17]

I have program that stopped functioning correctly after switching to Windows 7 64-bit back when it came out. The program loads, but past that, doing anything within results in the following error.

An attempt was made to load a program with an incorrect format.
(Exception from HRESULT: 0x8007000B)

Looking that up in Google, it looks like something about a .dll file that is 32-bit specific and short of actually re-writing the code to call on 64-bit .dll files, I can't find any solutions.

Anyone have any ideas on how to get this program to run?

If you can find which DLL it's after, perhaps it'll be one you can get the source to and recompile for a 64-bit environment?

Otherwise try to find a 64-bit DLL that contains the same functions (with the same names, unfortunately) and use it as a replacement.

It might help if you mention the name of the program. We are good..............but not that good.

The program is called csThumbnails. It's an older program that hasn't been updated in like, forever.

It is most likely making 16bit function calls, which are removed in windows 7. Means you will have to use xp mode or look for a suitable replacement.
