You must be on an administrator account, also install the latest .Net framework/updates if you are having issues.
This camera tool allows you to change the field of view and zoom level in guild of wars as the default is pretty low.
It uses auto-detection upon launch to fetch the address so should work for any region/version/patch for the foreseeable future.
Hotkeys:
Insert - Increase FOV
Delete - Decrease FOV
Insert + Delete - Reset FOV
Home - Toggle Extended Zoom on/off
End - Toggle First Person on/off (Zoom all the way in when this is on to get first person)
Version 0.2 Uses Autodetection and should work for any patch but takes a few seconds to scan and may not work for everybody
Version 1.0+ Uses a faster detection method but is less likely to survive patches.
The padding fix changes the threshold at which the camera bounces back and forth when it hits objects.
Someone on reddit made an FOV comparison video here:
