AllSync & AllDup

Older versions of AllDup had buttons on the Source Folders screen to Add Folder, Remove Non-Existing Folders, etc. Were they removed intentionally? Can I bring them back?

I can't update the OS with SP3. The only thing I can do is put the correct DLLs in the application directory if you can tell me which ones I need.

I don't have the option of reinstalling the OS. Can I put the necessary DLLs in the AllDup application folder? Which DLLs do I need?

Can you suggest some things for me to try to fix the problem? The error contains "CryptAcquireContext2" Should it be "CryptAcquireContext", "CryptAcquireContextA", or "CryptAcquireContextW"? Does that give a clue as to what might be wrong?

It's either SP2 or SP3.
fldrvw90.ocx is in the dep folder.

I get this error on Windows XP: "Can't initialize the crypt system provider CryptAcquireContext2" with AllDup 4.0.18. The application works on Windows 7. Am I missing a DLL?
