I got "vectorizantio failed" error to initiate CMS. Not using VBNET or else.

Is there any upgrade to do ? version 10.0.1110.116340.PE+.VC15.x64.CMS100

Check for updates at the CMS IntelliCAD 10 HELP > check for updates feature.

Message: "You have the latest version !"

Yes, the latest version: 10.0.1118.116743.PE+.VC15.x64.CMS100.

that's it 10.0.1118.116743.PE+.VC15.x64.CMS100

Go to the CMS IntelliCAD HELP Menu and CHECK for UPDATES.
Also try to switch graphics engine at CMS IntelliCAD from OpenGL ES to OpenGL. Your graphics card may require that.

On check for updates I got an Error Message from server obtaining the CMS Icad Version.

Using Intermediate Open Gl works fine ... until now...

Unsing checked Anti_alising (don1t know what it is for).
