Error: QuickBooks has a problem reading registration file qbregistration.dat

What is happening

When starting QuickBooks, the "Loading QuickBooks..." screen appears temporarily, and then the following error message appears:

QuickBooks has a problem in reading this registration file. You need to ask your system administrator to REMOVE this file and re-install QuickBooks

C:\Documents and Settings\All Users\Application Data\Common Files\Intuit\QuickBooks\QBRegistration.dat

Why is this happening

This error usually occurs if there has been damage to the MSXML component of Windows.

Other possible causes include:

  • Issues with User Account Control settings.
  • Having Norton 360 (or a similar Norton product) installed and running while QuickBooks is being installed or updated.
  • Corrupted QuickBooks installation files resulting from an incomplete "clean install."

Note: following these steps will not affect the data in your Company File.
