Unable to migrate .s7p project to TIA 15

Hi

Completely new to Siemens PLCs, so please bear with me.

I have a machine that had an upgrade from s5 to s7 about 7 years ago.

We dont have any Siemens software and didnt have the code from the PLC until today. I have managed to track down the contractor who did the upgrade and he has sent the project over.

I have downloaded a trial version of TIA 15 and tried to migrate the project. When I try to do this it comes up with the following error "There is no suitable STEP 7 version installed. Please install latest STEP 7 version."

Even though the following is installed

SIMATIC Products

"User Management Component x64";"V1.9";"V01.09.00.00_04.12.00.03"

Any ideas what I am doing wrong?

You need Step7 version 5.x installed too
Post the project
Maybe one of us can assist

I think you can install Step 7 version 5.x in evaluation mode and this will give you 21 one days to do all your portings.

Thanks both.
Waiting for authorisation to download the 5.6 version. Apparently can take a while to get this authorisation.
I’ll report back when I’ve tried this version.
