I still can't install with all the compatibility options mentioned before. I can't even run the galaxy client (what I was most interested) that installed without me knowing about it?

tried ity with latest installer version,the parameter did nothing for me also.

When I open the exe file, there comes error: The setup files are corrupted. Please obtain a new copy of the program. I did it about 5-6 times, but it changed nothing at all!
Please help me :'(
