Hi all

I'm running Simatic manager on My HP laptop " Core i5, RAM 4G " with Windows 7 professional 64 bit .

I have S7-300 CPU and USB PC MPI Adapter.

when I try to communicate with PLC, I can't see any drivers in PC/PG interface window as shown in the attached pic.

What can I do to fix this problem ?? if any one has a patch please attach it  

Hello,

delete the Folder /ProgramData/siemens/automation/Simatic OAM/data (ProgramData is a hidden folder, you must enable the show hidden Folders option in Windows Explorer)

Open a cmd Shell with adminstrator rights (cmd -> Run as Administrator)

type s7epaIMP64x.exe in the Admin shell.

Don't use the option -upd, do exactly was is writen in the steps above please!

5s in the search hear and you can find te solution!

Thank you MR.ChristophD

it's a great solution, Drivers Working now Properly  

Typing s7epalMP64x.exe in the cmd (even when run as administrator) doesnt do anything, it just says 's7epalMP64x.exe' is not a recognized as an internal or external command, operable program or batch file.

write command correctly then it work.

the comand is s7epaimp64x
