What do I do if I get the error message "Unable to register the DLL/OCX: RegSvr32 failed with exit code 0x5"

This message means that you're using either:

  • Office 2010 or above (64-bit edition): In this case, we recommend upgrading to PerfectIt 4 which is compatible with this edition. Alternatively, you can install the 32-bit edition of Office which is compatible with PerfectIt 1.
  • Office 2010 Starter: PerfectIt won't work with the Office 2010 Starter. We recommend buying a full version of Office. If budget is an issue, you could try looking for second-hand versions of Office 2003 and before (e.g. on eBay). These are usually inexpensive and are still excellent packages.
