Keep in mind that, while i can start the client and play a game, I can not update the riot client: "Update failed: Failed getting path to current executable: File path could not be found in a mapped drive: ??\C:\Riot Games\Riot Client\RiotClientServices.exe"...
I did a fresh install without a problem. Since the client updates immediately after the install, and that worked, I assume that other updates should work, too. Didn't have another update since then, though.
I now got an update and I got the same error.
Workaround: instead of starting LeagueClient.exe, start the installer and hit "Repair". This will install the update and start the launcher.
That should be Bug 51687. I'll send the patch there to the list one of these days now that the issue is more common.
