I am currently working on upgrading all systems to Win7 64-bit OS due to Windows dropping XP and we are to the point of really needing to update our software as well. So I am currently in the "testing phase" of this upgarde and I ran across an issue with RSLinx v.2.57 on Win7, there seem to be alot of drivers missing such as virtual backplane which I use with emmulate. Has rockwell put out anything to correct this issue, I haven't had much luck finding anything?
