Guild Wars 2

As my Guild Wars 2 folder appears to be a rough 2GB larger than my friends’ folders, I figured I’d reinstall and see if that remedies any crashing issues I am currently suffering from. Also, I played since the beta, so we simply suspect that the excess files consist of old things no longer necessary to run the game.
After all, these people play without crashing issues, on PC’s often worse than my own, and their client doesn’t seemingly require these 2GB of excess files

And so I went to peek, stared at the folder, went to my configuration screen and found…

Guild Wars 2 isn’t present on my PC.

Or rather, it does not detect it is installed.
It doesn’t pop up in the Program list, thus leaving me unable to uninstall, as the Guild Wars 2 folder itself also has no Uninstall application of any form or kind.

What am I to do now? Just do the oldskool delete with the trashbin, which is likely not at all going to remove it properly? Reinstall right atop the existing folder, and pray it overwrites or first removes the old stuff? Or is there something obvious that I missed?
Anyone got a clue?

You just have to delete the folder and then reinstall. I did the same…
