Bug: Can't remove "User Specified Programs" entry if program has been deleted
I added my 3rd party disk defragmenter (Perfect Disk) to the "User-Specified Programs" list under the Silent Mode Settings in the Miscellaneous options in NIS 2010 (22.214.171.124).
I have since upgraded Perfect Disk which removed the old version and installed the new version. I went to add the new version's executable to the "User-Specified Programs" and remove the old one and found that I could not remove the old one. No matter how many times I "removed" it, it remained.
I finally managed to remove it by copying the new versions executable to the old versions location. After that I could remove the entry. So basically the entry can only be removed if the file it's pointing to exists.
