Hello,
Thank you for your message.
Please try using this
Microsoft troubleshooting tool that can help to automatically repair issues when you're blocked from installing/removing/updating programs.
Simply download the troubleshooting tool, run it and follow the provided steps.
In addition, if the above doesn't help, please try resetting the Viewer's settings:
1. Fully exit the Viewer (
File→Exit).
2. Go to the
C:\Users\[Your_username]\AppData\Roaming\Remote Utilities Files\ folder. Note that the
AppData folder may be hidden by default in which case you'll need to turn on
Hidden files and folders in Windows Explorer settings.
3. Locate the file
config_4.xml and delete it.
4. Run Viewer and register it with your license key once again.
5. Try using the MSI Configuration tool and see if it works for you this time.
Hope that helps.
