Problem working with multiprojects with Step7 V5.7 + SP2 + HF1. ​​I had to install Step7 V5.7+SP2, in order to work on a project with the CP 443-1 Advanced (6GK7 443-1GX30-0XE0/V3.3). Later, when I tried to work with multiprojects file, Step7 V5.7 + SP2 + HF1 doesn't work properly, despite the fact that the previous version of Step7, V5.6, it can work without any problem.

Step7 Step7 V5.7 + SP2 + HF1 can open multiproject files, but they are incomplete and corrupted, it is not possible to work with them. (See attached files).

Please, is there any solution to use Step7 V5.7 + SP2 working with multiproject file?

Thanks in advance

Hello Emilio

Check the installation on your computer to see whether you still have option packages that you need to upgrade after installing STEP 7 V5.7 SP2 Hf1. The behavior you describe indicates an incompatibility. The FAQ also provides help:

Check the STEP 7 V5.x project for required option packages

You can also use the Compatool to check your installation. If necessary, you will then have to upgrade the corresponding option package.

Another workaround is to make a copy of your project using the menu command "Save as" with the option "With reorganization (slow)". Then continue working with the copy.
