- Click My Computer
- Click Edit > Find, and enter 7BBB4910-D21F-430F-92E6-7CA94CE3191C

To remove the Microsoft Visual Basic 6 Runtime, perform the following:
- Launch a Windows command prompt by clicking Start > Run > type cmd
- Change directory to C:\Windows\System32
For example: cd \windows\system32
- Enter the following command to remove the runtime library
