A couple of suggestions:
1. Use getenv("Temp") to give you a valid path.
2. If you are copying an EXE, I think you can get into trouble if you are trying to overwrite an EXE that is currently executing.

>Michael,
>The last time I had this problem there was no C:\Windows\Temp folder on the user's computer. If the user is running WinNT then their TEMP folder will be C:\WinNT\Temp. Or even another drive letter. This is not a folder that should be hardcoded unless you check it on setup - and even then users can delete the folder.
