I have lost all of my installed programs listings in the Add/Remove
Programs in the Control Panel.  That is, the dialog box is now empty.  Is
there a way I can refresh the registry to find my 32 bit installed
programs?  I do not have a good backup registry!
Is there a file outside the registry that contains the info I lost or is it all in the registry?                                                 Ruth Lowell

The registry keys for uninstalls can be found in....
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\UNINSTALL\[program].

I assume you have no entries here? You dont have a good backup but does the backup you have got any entries??

Most programs use a DE*.ISU file to uninstall. Do a directory search from the root and locate these files in each directory and you can create uninstall keys for all your software. Create a key under the above base key (in capitals) with the software title (eg MSWORD) then it needs 2 string values - DisplayName with it's value being the name that you want shown when you look at the list under Add/Remove Programs. The other string value is UninstallString with it's value being C:\WINDOWS\uninst.exe -fC:\[path]\DeIsL2.isu or whatever your DE*.ISU file name is.

The other option you can try is if your program directory contains WCMDR.EXE and WCMDR.INI. Replace the UninstallString value above with C:\[path]\WCMDR.EXE -iC:\[path]\WCMDR.INI

The final option you can try is if your program directory has SETUP.EXE. Many programs use SETUP.EXE /U or SETUP.EXE /uninstall
to start there uninstallers. Once again replace the UninstallString value above with C:\[path]\SETUP.EXE /u or C:\[path]\SETUP.EXE /uninstall  Try it from the command line first to see which applies.

This will get the majority of your programs all back into the list.
