Now, my problem with the SP8 is the "ACCESS POINT NOT FOUND" as of this one-->/tf/WW/en/Posts/81753 <-- where the patch luciferC4 provide seems not applicable.

This may have something to do within my laptop since I manage to install SP9 to the laptop of my colleague with the same software and even without the "ACCESS POINT NOT FOUND" problem! The only thing our OS differ is that his is Home edition while mine is Professional.

Can anybody help me?

------------------------------------------

A side question, we don't currently have a PC/PPI connector, can we use a USB/MPI one for the S7-200 CPU (PPI protocol)? We tried it on my colleague's laptop with SP9 without the "ACCESS POINT NOT FOUND" problem on PC/PG interface but it doesn't seem to connect. I actually tried it on the past but with Windows XP that's installed with PC ADAPTER USB, perhaps that's needed, but it seems there's no PC ADAPTER USB for Windows 7 64-Bit, or is there? And so, I've also installed Step7 v5.5 (which has integrated adapter right) together with my MICRO/WIN SP8 with "ACCESS POINT NOT FOUND" problem but it still don't communicate, perhaps the access point problem should really be resolved first? I'll try to install the Step7 v5.5 to my colleagues laptop without the accss point problem and see if it would do.

Thanks much!
