The diskette or the disk that you used to install the program. I don't have a c:\program filed\settings manager folder on my Windows XP machine (not even a c:\program files\settings manager), so I can't tell you where it comes from.

More info on that program in http://www.freefixer.com/library/file/sysapcrt.dll-111332/ : it comes from Aztek media and it might be malware. So - given that info - it might be time to do what Grif recommends in http://forums.cnet.com/7726-6122_102-5509131.html if you didn't install it yourself.
