Fixing QuickBooks Login Errors

To resolve the errors, follow these steps:

  1. Configure QuickBooks to accept automatic logins from the SmartVault software:
    • Make sure you're in QuickBooks' single-user mode. To do this, click File and check if the Switch to Multi-user Mode option is displayed. If it is, you're in multi-user mode. Click Switch to Single-user Mode to switch.
    • If your SmartVault Desktop software has been upgraded from a version prior to SmartVault 3.0, you may need to modify both instances of SmartVault in the Integrated Applications dialog box.
  2. Right-click on the SmartVault icon in the system tray, then click Exit.
  3. Open QuickBooks and log in as Admin in single-user mode.
  4. In QuickBooks, on the Edit menu, click Preferences.
  5. In the left pane, click Integrated Applications.
  6. On the Company Preferences tab, select SmartVault and then click Properties.
  7. Select the Yes, always; allow even if QuickBooks is not running checkbox, and choose Admin as the Login user.
  8. Click OK and then click OK again.
  9. Close the QuickBooks company file.
  10. Open the QuickBooks company file as a non-Admin user, and sign into SmartVault when the login page appears.
