This problem can occur if the program you installed creates a registry key name that is longer than 60 characters in length. Add/Remove Programs only lists program names it locates up to the point it encounters this situation.
Please be caution to edit registry key since it's very important. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, please kindly check this article.
To work around this problem, use one of the following methods:
Method 1 Use the Uninstall Command Displayed in the Registry
- Use Registry Editor (Regedit.exe) to view the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
- Double-click the UninstallString registry value, copy the contents of the Value Data box by selecting the contents and pressing CTRL+C, and then quit Registry Editor.
- Click Start, click Run, press CTRL+V to paste the uninstall command, and then click OK.
Method 2 Shorten the Registry Key Name
Run Regedit.exe to view the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Click the registry key for the program you installed, click Rename on the Edit menu, and then use a name with less than 60 characters. Note that if the DisplayName value is longer than 32 characters, it is not displayed. To rename it, double-click DisplayName and use a name up to 32 characters in length.
