Installation of simatic s7 software


Thread Starter


I have downloaded one siemens plc software "step7 microwin v40 sp7" from internet using the following link.

I am facing some problems during the installation of it . It says "searching local drives for valid installtion" and then when i am selecting any drive it says "file not found" and quits.

I do not know what to do? I think for installing this software one should have the older version of it.

pls help me in this regard...

Thanking you
You have only downloaded the Service Pack Update. Here is an extract from the link you provided:

*"The prerequisite for installation of the STEP 7-Micro/WIN V4.0 Service Pack 7 (SP7) is an installed and running earlier version of STEP 7-Micro/WIN V4.0 on your PG or PC.

After you have downloaded the STEP7-MicroWIN V40 SP7 unzip the file. Then browse to the folder where you have unpacked the STEP7-Micro/WIN V4.0 SP7 and double click the Rejoin.bat file. "*

Hope this helps,

Hi Patil,
I download the software from the link you mentioned,
Its seems a additional service pack but not the complete programe.
You need t have the old version installed in order to install it.
