Hello there, tizbuddez.

Thanks for letting us know. Let me help you get this sorted out to keep your QuickBooks running and so you can get back to your business. 

Here are some possible causes of this error: 

• Outdated Windows operating system or an anti-virus program that quarantines some QuickBooks Desktop files.

• A component or file needed by QuickBooks Desktop to run is damaged or missing. 

QuickBooks Desktop installation can fail or become damaged once the windows updates are not installed. Let's ensure that your windows is up to date.

Here's how:

2. Select All Programs and click Windows Update.
3. After installing the updates, install QuickBooks. 

Now, you'll need to process troubleshooting steps by deleting the EntitlementDataStore.ecml file to resolve this issue. You'll need to Close your QuickBooks Desktop first and ensure that all QuickBooks processes are no longer running.
