Try clearing your %TEMP% folder, Graal likes to store things in there before copying to where they're supposed to be.

If you have an AV with real-time protection try disabling it as well or adding the extensions of files to the list of exclusions you're downloading to it.

I've had issues with earlier versions of Graal and Microsoft Security Essentials probably because of the way it was packed but it affect the loading times of the program.

Try going into Safe Mode with Networking and trying RC there, if it works then you should be able to narrow down the program causing the crash.

You can also try renaming RemoteControl2 to something else like RC2.
