If you install the IDMU Administration Pack on Windows XP Professional, use Control Panel / Add or Remove Programs to remove it, and re-install the IDMU Administration Pack, you cannot use Control Panel / Add or Remove Programs to remove it again, because of a problem in the IDMU Administration Pack installer.

To workaround this behavior:

1. Open a CMD.EXE window.

2. Type the following commands, pressing Enter after each line:

cd /d %windir%\Idmusnap
regsvr32 /s /u nisprop.dll
del /q /f /s *.*

3. Delete the registry sub-key:

For x86-based Windows XP

REG DELETE "HKLM\SOFTWARE\Microsoft\Updates\Windows XP\SP\idmu" /F

Where is your current service pack number.

For x64-based Windows XP

REG DELETE "HKLM\SOFTWARE\Microsoft\Updates\Windows XP Version 2003\SP\idmu" /F

Where is your current service pack number.

NOTE: Every time you remove the IDMU Administration Pack, you must delete the IDMU registry sub-key.
