Not able to find access point for microwin

I am having system with Siemens TIA portal V12 and Simatic Step 7 software installed. Recently i tried to install microwin. Installation is happening  whereas in PG/PC interface I am not able to find access point for microwin. I guess PG/PC interface is conflicting with one of the above installed software. How to solve this problem. I am getting an error if i try to set PG/PC interface "Specified access point not found".

Note: I have installed the microwin in another windows7 64 bit system. During installtion, I got an error but after updating to SP9, it is working fine.
