Locating catalog problem

[WHows]

Hello,

After resolving a missing workspace problem, I keep getting the message 'Could not find file C:\structural_catalog.acat' whenever I am trying to implement structures into my drawings.

Is there any way to modify or point to the corect folder which contains these .acat files?

I even changed the variables P3dContentRootpath and ConfigFilePath using Windows Registry to contain the correct path.

So far no positive results.

Thanks,
