Welcome to the STEP forum.
Firstly the wiki says in the 'Initial Setup' section:
- Turn on the Archive Invalidation method appropriate for your game:
- If running any game that is not Skyrim, click the profile button in the toolbar and check Automatic Archive Invalidation. Repeat this for all new profiles you create.
- If running Skyrim, click the wrench button, go to the Workarounds tab, and click Back-date BSAs.
Therfore you don't need to check that if you are using Skyrim, as you state you are.
Secondly I cannot replicate this with any of my installations. All profiles, whether new or existing, allow me to check that option.
Could you check the installation to ensure nothing is out of place? Perhaps if you could provide the paths to MO, Steam and Skyrim in addition to you Windows environment.
Unless we can get this information it will be very hard to pinpoint what is happening and even if a bug report is made all this information will still be needed.Go to the full post
