You can have this message

Example:

Or this message :

Known Cause(s):

• You did not buy the anniversary edition addon
• You don't have a legal copy of Skyrim
• The game has not been updated to the latest version available from Steam.
• The Skyrim Steam installation directory you referenced in the installer is not the one that have the latest Steam Skyrim Anniverasry Edition (it can happen if you have several Skyrim installations)

Troubleshooting

1. Make sure your Bethesda account is linked to the Steam account that owns Skyrim - you can do this on the Bethesda site. (There is an issue with family sharing when downloading the CC content, so use the account that owns Skyrim when doing this.)

2. Double-check that the folder where Skyrim is installed is the same folder shown in the error message. If it's not, open NolvusDashboard.ini to adjust the GamePath accordingly (without the ending backslash)

3. Run Skyrim from Steam, go into the Creations menu, and click Options. Use this to Delete All Creations and then Download All Creations - even if you've done this step before. For reasons unknown, sometimes the game appears to be downloading those files when it actually isn't, so this forces it to try again.

4. Close Skyrim and try your dashboard again.

If it sill does not work

1. Open your Steam Library and uninstall Skyrim (Right-click -> Manage -> Uninstall).

2. Open explorer and browse to the folder where Skyrim was installed (it will still be there).

3. Delete everything left inside this folder (this step is crucial).

Example: open explorer to [YOUR_DRIVE]:\SteamLibrary\steamapps\common\Skyrim Special Edition and anything left in there must be manually removed.

4. Reinstall Skryim

5. When Skyrim is installed, click play and download all CC content.
