Okay so I have looked through the articles and I found one that was on this topic but it was a number of months old and it didnt fully help me. See my problem is that when I try to instal RMXP it gives me this error "cannot verify key UNKNOWN\RGSS.Archive\shell\open\command\" and I dont know what it means. Now in the topic I found it said I should delete all the dlls from any old or not legal versions of RMXP that I may have had at some point. I did this but it still doesnt work. SO is there anything that you can do to help me? Someone had said they solved the problem but was nto clear about how they did it and I PMed them but they have not gotten back to me yet.
