Maybe you can search.
The Add/Remove Programs file is appwiz.cpl and is opened by Control Panel, through some mysterious process. Its location: C:\Windows\system32
There may also be a backed-up copy in:
Or, you might try replacing it with the file from your
installation CD, though, if you've applied Service Packs,that one may be outdated for your present installation.Still, it might work anyway, as a last resort.
You can always run a search on your C: drive for the
appwiz.cpl file, and see what other copies you can find,and compare their size and date with the one in system32.

Running XP Pro SP2
Entries keep disappearing from Add and Remove Programs. Right now there are four in there. I have not been able to determine what is doing it. It has happened three time now in two days. So far I've been using System restore but I need to find out what's causing this to happen.
Last night after a system restore I installed Zone Alarm (for 2nd time) and A&R Programs was fine after that and this morning. This morning I installed Sypbot Search & Destroy and A&R Programs were fine afterward and later.
A while ago I opened A&R Programs and all but four are missing again.
I have googled the problem and there seems to be a gadzillion solutions none of which seem to apply to me or the person that asked for help.
Does anyone here really know what causes this to happen and how to fix it?
Something I'm curious about, one person said their entries were gone and they uninstall some type game updater and the entries returned! Am I to understand that although the programs are not showing in the applet they actually are ''somewhere'' and not really gone? Can they be restored without doing a system restore?
Thanks for any help.
