How to Fix - "Unable to Open Seed Exclusively! Cannot Create Project Database!” Error

 

"Unable to Open Seed Exclusively! Cannot Create Project Database!" Error

Issue: “Unable to Open Seed Exclusively Cannot Create Project Database” error appears when opening a new project in Skyline.

Additional Information:

  • In early 2020 Microsoft released an update for Windows which appeared to cause issues with the Microsoft Access Database Engine. A quick re-install of the engine will fix the error.

 

 

Resolution:

  1. Close AutoCAD and Skyline
  2. Open start menu
  3. Go to Control Panel
  4. Go to "uninstall a program"
  5. Uninstall Microsoft Access Database Engine 2010 or 2016 (if you have 2007 installed, uninstall as well) 
  6. Reinstall Microsoft Access Database Engine 2010 or 2016 (reinstall Microsoft Access Database Engine 2007 afterwards if needed)
  7. Relaunch AutoCAD and Skyline
