--- Comment #1 from Borislav Sabev badganaka@gmail.com --- Did you try installing AdobeAIR? It is required by the LoL store. This should NOT affect the in-game store - just the one in the launcher.
Please try installing Adobe Air and retest. A lot of people got it running. You will also need: ms-corefonts & vc2005/2008.
