Glad to have you here in the Community, @jburris.

I would like to share some insights on how to resolve the errors (-6129, 0) that occur when creating a new company and opening it in QuickBooks Desktop.

Firstly, this error message is related to folder permissions. If the file was saved to the network, the folder where the file was saved should have full access instead of being restricted.

Open the sample file and save it with a new file name. Replicate the process to open the company file multiple times. Did you encounter the same error message?
