I restored my registry via the recovery console. I restored from an old file. I have some installed programs after the restore file's date and now those programs don't show up in "Add-Remove Programs" or in the Start Menu I can see them in the C:\Programs folder but they don't run if I try to click on the program's .exe file from there. Nothing happens; I know it's because of missing registry files due to the old restore file. How can I uninstall those programs or get them to work again?
