If there is a key stored on your computer, manually remove the license key entries in your computer's registry to get the new key to work.
Note: This process requires Administrator rights. It also requires the adjustment of the Windows Registry.
- Choose Start > Run.
- Type "regedit" and click OK.
- Navigate to: /HKEY_CLASSES_ROOT/CLSID
- Look for and delete {F18C1202-9D2E-4BE4-AB18-99C7E870D28A}
- For newer style keys (64-bit windows), there is a second location as well:
- Navigate to \HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID\
- Look for and delete {F18C1202-9D2E-4BE4-AB18-99C7E870D28A}\Licenses
- Close regedit.
- Rerun the new .reg file once more if trying to resolve a new license key issue.
