After the upgrade to a Windows NT 5.x operating system, some applications whose shortcuts were stored in the Administrative Tools folder, like the Visual J# .NET Redistributable Package, are not listed in the Control Panel / Add/Remove Programs applet. Thus, you cannot uninstall the application and you can't reinstall it.
The location of the Administrative Tools folder is different in various operating systems. The upgrade did not change the registry entry that points to the new location.
To resolve this issue:
1. Copy / Paste the following to a AdminToolsFolder.reg file:
REGEDIT4
\[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\]
"Common Administrative Tools"=-
"Common Administrative Tools"="C:\\Documents and Settings\\All Users\\Start Menu\\Programs\\Administrative Tools"
\[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\]
"Common Administrative Tools"=-
"Common Administrative Tools"=hex(2):25,41,4c,4c,55,53,45,52,53,50,52,4f,46,49,\
4c,45,25,5c,53,74,61,72,74,20,4d,65,6e,75,5c,50,72,6f,67,72,61,6d,73,5c,41,\
64,6d,69,6e,69,73,74,72,61,74,69,76,65,20,54,6f,6f,6c,73,00
2. Merge the AdminToolsFolder.reg file with the registry or run regedit /s AdminToolsFolder.reg.
3. Locate the applications installer package, such as C:\Program Files\Common Files\Microsoft Visual J# .NET Setup\VJSharpRDP1033.msi, and double-click it to perform the uninstall.
