It suggested reinstalling the program to potentially resolve the issue
Why did you try to manually copy files and not reinstall the program?
Some programs are designed to be portable where you can just copy the .exe file one pc to another and just run it. Other programs have dependent dll's and those dll's may themselves depend on other dll's. And registry entries, and folder permissions, and config files, etc.
The correct way to resolve that problem is to run the .MSI install file or setup.exe that properly installs the program.
It appears that you put a 32 bit dll into the 64 bit folder or vise versa.

I would recommend undoing whatever file copies that you did and contact the developer and get the correct install files.
If the application is no longer supported and an install setup.exe does not exist, then you should first try to find a different, supported program that performs the same functionality.
The last resort would be to run Process Monitor and see what files the .exe is looking for and try to manually replace the files.

The last dll that it loads before the 0x000007b error is probably the one with the wrong bitness.
