Add Remove programs

Clarifications

Sometimes you need to re-register the call;

REGSVR32 APPWIZ.CPL

Other times a program installs leaving a negative number in the uninstall registry location; (esp autocad)

Run Regedit then navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Look for a subkey "DisplayIcon entry with either a blank or a -1, edit the entry to 1

1) Log off, then re-logon.
2) If that doesn't work, restart the computer.
3) If that doesn't work, type this in the Run menu:

chkdsk C: /F and hit [i]Enter[/i]

Windows will check the sectors for errors, and [i]fix[/i] any found errors at the next boot.

4) If that doesn't work, locate a [i]restore point[/i] when the computer was working properly, and use System Restore.

5) If that doesn't work, back up all your personal files, and run the Files & Settings Transfer Wizard (old computer). Save this settings folder to a USB flash drive, external hard drive, or CD for safekeeping.

Now insert the operating system installation/recovery CD and [i]repair[/i] the Windows installation (if you have a [i]repair[/i] option).

Please post back in this thread and let us know what worked for you (or what didn't work).
