The more things change the more they stay the same...
Recently installed a beta client for a certain game launcher (yes, I have a gaming rig, I've got a few macs and two servers at home. Don't judge me) and discovered it wouldn't start... No problem I'll just uninstall and reinstall...
Yeah, no...
This started an hour long tearing through various locations, cache directories and regedit before finding that CC cleaner (I was getting desperate by this point) deleted the recycle bin by default removing a folder I needed for the actual solution (uninstalling via a cached msi).
Got it sorted with some file recovery magic but still far more buggering around than a game client should ever require.
Gimp icon because I must be to continue to pay them money for this crap...
