Catalog Builder Error

[Anonymous]

When attempting to create a new catalog from an excel document, I'm getting the error "Invalid Family Sheet" for10 differant sheets. What does this mean?

Are you manually creating sheets inside of MS Excel If so, this may be your problem?

I am beginning to think it is a rights issue, after a Win10 update this spring/summer.

Digging deeper I am finding random empty support folders from the various attempts.

And the dates are after the updates..

The original was.

And was a working catalog for a number of years.

And I tried exporting the old catalog and reimporting.

Then it said the drawing path was missing.
