Hello,

you must install Startdrive V15.1 if you use TIA Portal V15.1

While the project was still in V15, it sounds like someone installed startdrive v15 and poked around with using it for the project, then decided to stick with using Starter instead.

If you still have the V15 project and have V15 available, you can recreate the project in V15 by dragging the PLC / HMI over to a new TIA Portal V15 project, and it _might_ get rid of the dependency on Startdrive. 

If you do not have V15 or no longer have the V15 project, you will need to install V15 and V15.1 of startdrive (my educated guess).

If it were me, I would also submit a Support Request with Siemens.  Attach an archive of the V15.1 project, link to this forum thread, and a copy of the original post in this forum.  They may be able to remove the startdrive restriction by some trick they know.  If not, they know about the problem and maybe in the future can fix it.

Lastly, if you do not have the latest update to V15.1, please install it.

hello,

we were using S120-cu310 with starterv5.1 and TIAv15.0 for our system . recently i had to update the TIAv15.0 to V15.1 . after installation i cannot open the project anymore as it requests an installation of Startdrive v15. i have already tried installing the starter v5.1 like in the system before,but no use. what can be an easy solution to this .
