So I managed to run the GOG version of the game with your collection(I have now 3 copies of the game because copy with PL localization from TES anthology is unmoddable, steam have broken shopping page - if You have GOTY u can't but GOTY deluxe).
Everything went like You described
I endoresed the collection
Thank you very much, Ergon4321. I really appreciate you taking the time to let me know about the issue you were having. It helps me to make the collection better for everyone. I was able to identify a bug in Vortex that affects players when creating new profiles during the installation process for a collection due to your help. I have entered a bug fix to the Nexus team for this, and updated the collections description page to make it clear to avoid this.
In recognition for your help playtesting the collection, I have added you to the Credits section. Also, I really do appreciate endorsements and up-votes as well! Take care, and let me know what else you encounter in the game that doesn't seem right.
