Hello to all, I resolved my problem. I think, as I said, the problem is (what I think of) the Windows language. I tried all solutions on forums (on Gameex) but I had no solution. Then I tried to change Windows default language but as I said on my previous messages, my Windows (Vista) is in Turkish and I have no solution because of non ability to change language on my installed Windows. Then I bought and installed Windows 8 (in english) and then when I installed gameex, I have no problem (the destination folders are the same as previous) with Mame games. I am neighter a computer engineer nor a coder but what I think is the problem is the difference of language. Please check the iterations again because in Turkish, i and I are 2 seperate letters. Also thank to Tempest and Dazzle HP for your helps for solution on my problem.
