It's recommended that you allow QuickBooks to move your company data file from the Program Files folder to the default data file location used by QuickBooks:
C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files
To move the file using QuickBooks, open the company file again and click Move in the Move Company File window.
If you want to open a company data file located in the Program Files folder, you must run QuickBooks with a full administrator access token. Refer to Windows Help for detailed information about access tokens.
