I made a project using Ignition 7.9.17 on my computer.
At the end, I made a backup and I tried to restore it on another gateway 7.9.17 installed on the customer computer.
After opening Designer and traying to save a UDT tags changes, I got error displayed in the attached photo.
Also, I noticed that all Expression type tags not work and their quality was Unkown in the new gateway however they work correctly in the first gateway on my computer.
So, I had the idea to create a new Scan Class for the Expression tags identical to the Default Scan Class and there the Expression tags worked again.
How can I fix his !!!
