Catia 3D V5 R22 and Windows 10

fmunier · June 5, 2019, 8:44am

Hello

we use Catia 3D v5 R22 in our school, on Windows 7 pro machines.

We need to update to Windows 10. Once the update is complete, Catia will no longer launch.

When you launch Catia, nothing happens, but a Catia process appears in the task manager and takes up 99% of the CPU.

I tried to put the shortcut in Windows 7 compatibility mode but it doesn't change anything.

Do you have a solution to help me out?

Thank you.

I had the same problem, I solved this one by going back to Catia V5R20 and not R22.

Hello

The best advice is to upgrade to a W10-certified version.

Otherwise see the two answers on the forum.
