Hi!
I have spent all day trying to solve the RADS problem.
Now when the client is "RADS"* there is gonna be problems for all who install:
Microsoft .NET Framework 4 Client Profile for Windows 7 x64-based Systems (KB982670)
Do not install this until it's solved by the Riot team.
If you have it installed and you cant start the launcher do this:
Control Panel --> Uninstall programs ----> Microsoft .NET Framework 4 Client Profile --> Uninstall
PS. this is only if you use x64 Windows 7 (if you dont know you prob dont have it).
* Rapid application development: http://en.wikipedia.org/wiki/Rapid_application_development
Tried repairing the files at all assuming you can open the client to the launcher at least if so then press the cog in the top right corner and run the repair tool then try.

Download this shiz i seen on google people said it worked for them... Fk noes why it has to be Japanese version though.
Guessing the usual crap of running as admin etc didn't do anything so i'd try a clean install see if that fixes anything if you still have nothing after that drop a support ticket in through their website. They're usually pretty good with it.
