Dear Sir 

Good Day!

------------------------------------------------------------------------------------------
Split from how to install STEP7-MicroWIN in windows 10 64bit.

Hi,

Do you hav a previous version installed on this PC?

If not, it´s a normal behaviour.

INSTALLATION INSTRUCTIONS 

1. On the computer with the executable predecessor version zip the file microwin.exe. You will find it with the standard installation in drive C in the folder:
Program Files\Simatic\STEP 7-MicroWIN V4\bin
2. Copy the packed file to the computer with the new operating system and unpack the file.
3. Start the installation in line with the installation instructions of the relevant Service Pack.

Regards,

Towome

-- added detail for clarity

Siemens does not supply a download for the full version of the Microwin software. Only the installation for the upgrade is available for download from Siemens' web site.

The problem comes that only the newest iteration of Microwin can install on 64-bit Windows. So either a full software installation disk is needed or a previous installation from an older computer is needed. Mr Towome detailed the exact procedure.

The original S7-200 has been off the market for several years already. You will need to contact Siemens if you are not able to follow the given instructions.

I recommend that you install on Windows 7 as installation on Windows 10 is known to give problems. The program cable drivers is especially a headache. Better option would be to install on 32-bit based Windows XP or Windows 7.
