Resolving sign in completion failure in Lacerte

SOLVEDby IntuitLacerte Tax1Updated July 26, 2021

When opening the 2017 or 2018 Lacerte program, you may encounter the following error:

Sign In Completion Failed:  The Type Initializer for "Intuit.Spc.Authorization.Internal.DeviceIDProvider" Threw an Exception.

You may also find that after entering your credentials, the sign-in window closes and the program never opens.

How to resolve sign in completion failure

An update in Lacerte 2017 changed how the program handles errors with the sign in screen. Instead of logging errors with the Windows Management Instrumentation (WMI) service and continuing to sign in, it displays an error message and stops the sign-in process.

There are two possible solutions Lacerte recommends that may require your local IT professional.

Solution no. 1: check if your computer has enough RAM

  1. On the Desktop, right-click This PC and select Properties.


  1. Hold down the Windows button on your keyboard.
  2. Press the Pause/Break button.

The processor type and installed memory will appear under the System section. 

If the Processor and Installed memory (RAM) shows "Not Available", have your IT Technician try the steps from this Microsoft Community article.  

After completing Method 1 listed in the article, reboot the computer and then try opening the program. 

If the issue persists, complete Method 2, reboot the computer and reattempt to open the program.

Solution no. 2: check if your Windows Registry contains a bad location

If you have RAM available and you've tried Methods 1 and 2 but you still experience the same error, the problem could be a bad dll path for the cimwin32.dll.

This Microsoft TechNet post includes the impacted registry key. We've found that renaming the key by adding -bad resolves the issue:

  • Before: HKEY_CLASSES_ROOTWow6432NodeCLSID{D63A5850-8F16-11CF-9F47-00AA00BF345C}
  • After: HKEY_CLASSES_ROOTWow6432NodeCLSID{D63A5850-8F16-11CF-9F47-00AA00BF345C}-bad
