This seems like the typical error that appears when you run a 16 bits program inside a 64 bits Windows.
All 64 bits versions of Windows have dropped compatibility with 16 bits programs and don't run them at all.
You may install a virtual machine to bypass this limitation if absolutely needed or get a newer 32 bits version.
Also, many old programs often are 32 bits, but their installers are 16 bits based, so they won't install, but run properly after it if you manage to get the files somehow. Most likely this is the cause of the error.
