Hello, I was quite excited the other day when I saw that Nehrim was finally on steam, however, I haven't been able to get it to work and am faced with the same error when I attempt to update it in the launcher, I have them both on the same drive and they should both be in the steamapps folder. I will include a screencap of said error. Any help would be appreciated. Danke schön meine Freunde.

Some other process is locking the files. Were any folders opened in the background? You could try to restart your computer and try it again.

Hello, I restarted my comp and got the same error. I made sure that the only programs I had open were the steam launcher & The Nehrim launcher before pressing update. It usually starts up fine but states that I need an update to play, and then the error shown above occurs. Is there any other way I could potentially fix this?

for a test: Activate Oblivion with the switcher and close the switcher afterwards. Then start the update directly via Steam.
Then activate Nehrim again with the Switcher and only now start the Nehrim-launcher.


Otherwise:
Check if you have under ...\Steam\steamapps\common\ the folders: Oblivion and Oblivion_Backup (only exists when Nehrim is active)
well as Nehrim and the subfolder NerimFiles (the latter only exists when Oblivion is active) in .

Start the NehrimLauncher.exe once with administrator rights (can be set under file properties).

Make sure that no write protection exists on the folder:
...\Steam\steamapps\common\Oblivion as well as C:\Users\...\Documents\my games\Oblivion.

Any antivirus program(then put it on the whitelist), Windows - devender or general Windows rights could also block this
(if e.g. , as mentioned above, an open file in named folders)

I experienced a similar problem with Nehrim -- hence the reason I am replying here rather than starting a new thread. However, I was not getting an unhandled exception error, just that "switching" to Nehrim would fail with a suggestion to check folder permissions and possibly restart my computer.

This behavior did not begin when I first installed Nehrim. Instead, Nehrim would not launch after I "switched." Instead, it would crash on start-up. As a result, I "verified" Oblivion files through Steam and tried again. That didn't help. Then I uninstalled Nehrim and Oblivion. Trying again, the Nehrim launcher refused to "switch" to Nehrim and started complaining about folder permissions. That sent me down the Windows 10 permissions/UAC rabbit hole complete with several uninstall/reinstall cycles, including the manual removal of residual Oblivion directories after uninstalling within Steam. Nothing worked...until it finally dawned on me that the Oblivion_BACKUP folder was a result of my previous attempt to run Nehrim and not from the modding process for Oblivion when I last played it months ago.

In summary, "switching" can fail if an old Oblivion_BACKUP folder still exists when trying to "switch" from Oblivion to Nehrim. This is an obvious problem in hindsight, but the error dialog put up by the Nehrim switcher/launcher should have reported an existing Oblivion_BACKUP folder as the source of the "permission" problem rather than a more generic problem.

Thanks, figured that too and will be fixed.
