Hey there Gluon – Do you happen to have the rest of the crash report? You can find this by navigating to Documents\Guild Wars 2 and it’ll be the ArenaNet.log file. You can attach it to the thread by clicking “More posting & formatting options…”
I don’t have much to go on with what you’ve provided, but just to start, I would like you to try the following steps:
1. Navigate to your Guild Wars 2 folder, which by default should be C:\Program Files(x86)\Guild Wars 2.
2. Move this folder to a new location like C:\Games\Guild Wars 2. The location doesn’t matter specifically, as long as it’s outside of Program Files and Program Files(x86).
3. Navigate to this new location and “Right-click” on “GW2.exe” selecting “Create Shortcut.”
4. Rename this shortcut to “Guild Wars 2 Admin Mode.”
5. “Right-click” on “Guild Wars 2 Admin Mode” and select “Properties.”
6. Click the “Compatibility” tab.
7. Checkmark “Run this program as an Administrator.”
8. Click “Ok.”
Once completed, let’s go ahead and repair the new installation location:
1. Right-click on “GW2.exe” and select “Create Shortcut.”
2. Rename this shortcut to “Guild Wars 2 Repair.”
3. Right-click on this shortcut and select “Properties.”
4. Edit the “Target” line to include -repair at the end.
Note: Please make sure -repair is outside of the quotes
Correctly Formatted Example: “C:\Games\Guild Wars 2\GW2.exe” -repair
Incorrectly Formatted Example: “C:\Games\Guild Wars 2\GW2.exe -repair”
5. Once completed, click “Ok” to save your changes.
If you get an error trying to save, your target line may not have the correct format. Please try step 5 again.
8. Right-click “Guild Wars 2 Repair” and select “Run as Administrator.”
Allow the repair to run and once completed, double click on “Guild Wars 2 Admin Mode” to launch the game.
Hope this helps!
