I do not have the original CD, but the program is on an internal hard drive, but I have a second internal hard drive inside my desktop that I want to transfer the program to. How can I do this?
That's not an easy thing to do. Many Windows programs are not just an EXE file anymore. Besides the EXE, there may be DLL's, config and ini files, and registry settings.Trying to figure it all out can be trying.
You could find the program's foldrin the Program Files folder. Then move (better: copy) the whole folder over to the other drive. You may get lucky and have it work. Or not.
The better way to do this is to look for the program as a download on the internet and just re-install to the 2nd drive.
