Anyone who recently wanted to uninstall the PC beta of Fallout 76 must have been shocked. Because currently, the Bethesda launcher refuses to do so. You are required to buy the game first.
After there was a massive bug during the beta, where the beta files could delete themselves, the next problem has now emerged.
The beta of Fallout 76 cannot be uninstalled normally, as long as you haven’t purchased the game yet.

First the beta deletes itself, now it doesn’t want to be deleted
What happened? Several players are reporting on Reddit and in the official forums that they cannot uninstall the beta. Only an error message appears. It states that access is denied. You should log in with an account that has already purchased the game.
Currently, there isn’t even an option to uninstall in the launcher. On PC, Fallout 76 can only be purchased through the Bethesda launcher, a release via Steam is not planned.
At the moment, there seems to be no solution to the problem affecting some players. Some players are already complaining in the Fallout 76 subreddit and Bethesda forum.

Community suggestions: Some suggest uninstalling the game simply through Windows. However, that also doesn’t seem to work, as the Bethesda launcher then opens with the same error message. It’s not clear from the postings whether any external uninstall programs work.
Some hope that the option will be automatically activated on November 14, the release day of Fallout 76. Some are already joking that the beta might self-delete again on the release date of the full version.
The beta of Fallout 76 takes up about 50 GB of hard disk space. The finished game will likely take up more space with the Day-1 patch.
