Intuit strongly recommends you not update a company data file across a network connection. Copy the company file to a local installation, open the company file and allow the update process to complete, and then close the file and copy it back to the network location.
Some QuickBooks updates will include a change to the data file structure. When opening the company file for the first time after installing a product update, you may see a progress bar as the structure change is implemented. It is important to allow this change to complete; do not end task on QuickBooks during this process.
