I just consulted a collegue (jrdenver, thanks for your help
If you are not using a sql server or any program using a sql server you can remove this:
Microsoft SQL Server Desktop Engine (RETSDATA)
Reboot to save mode.
- Click on the configure button on the bottom right
- Click on the tab "Misc Tools"
- Click on the Box that says "Uninstall Manager"
- Click on the entry you wish to delete
- Click on Delete this entry
- Click "Yes"
Reboot back to normal mode.
Let me know how things are now.
