You must reinstall them.
There are a few programs that you can just move the folder.
I tried googling this question but as you might imagine the results pertained to recovery programs for crashed hard drives.
I'm just wondering how to recover and install programs I have from a previous hard drive (now external) to a new computer (programs such as Smith Micro Anime Studio, Adobe Photoshop, Microsoft Office, etc.)
I appreciate your time and knowledge.
