That is the problem sometimes with installing add on programs to another partition...when you reformat whatever they plugged into the system/system32 folders goes missing.
Here is what I've done in the past.
Keep your saved stuff on the other partition for now. Reinstall the programs to your new OS, this will replace the dll files or whatever it is that is missing to make the programs work.
Copy the contents from your saved stuff into the newly created folders and see if it works.
I've used this method to port over several programs from old OS installs to new ones.
Hope it helps you.
