to delete was refused - in safe mode - no option to do it as admin?
I'm sorry, but is should work in Safe mode. However, as I've said, I never tried do it personally: I only read other users saying this fixed their problems with faulty Simconnect installs.
Other things you can try are:
- If you have FSX installer, REPAIR its installation
- Reinstall Windows
I realy need these simconnect files to aktivate your sceneries?
Please don't make it sound as if this is an FSDT sceneries issue. With a corrupted/missing Simconnect, NO ADDON will work, except the simplest ones that don't require any software support modules. You had the same, identical, issue with the VRS add-ons so, clearly you want to have this fixed, otherwise you'll have endless problems with all sort of other add-ons too.
