Hi, when i where going to Archive the current V15.1 project, TIA portal starts to crash when i try open the original project (of which i tried to create an archive of), tried moving it to another place, still crashing on this project.

So i figured, ill try open it in V18, but then it popsup stating V15.1 Upd3 is required, but it is installed

Left side is V15.1, Right Side is V18.

Also, why would the project now all the sudden start crashing tia portal after i pressed Archive in the file menu (here it crashed the first time, instantly)

Now i cannot even open the project anymore.
