Even the path displayed is the same as in the previous picture?
I really don't know why it won't work... I tried it with the same OS and UAC setting as you appear to have and I didn't have a problem either with the launcer or changing the resolution for the Steam version of Nexus.
Let's try it manually again:- Open up regedit.exe
- Navigate to both of the following paths and note the values for "Display_Width" and "Display_Height" for each of them:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mithis\Nexus - The Jupiter Incident
HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\SOFTWARE\Wow6432Node\Mithis\Nexus - The Jupiter Incident - Start up the game through Steam
- Open up the options menu and change your resolution to something else
- Close the game
- Use regedit.exe again to navigate to both of the previous paths and try to identify the one where "Display_Width" and "Display_Height" now show different values than before
This should be the correct registry key, where you can set your new resolution. To do so, change "Display_Width" and "Display_Height" to the new values, e.g to 1920 and 1200.
Important: When entering the new values, make sure "Decimal" is selected before entering the new number. This option is set to hexadecimal by default and if you were to enter 1920 into the box, you are actually telling the game to run a resolution 6432 pixel wide.
