Install

I want to fix this from happening to you, @John_K.

Let's fix your multi-user issue in QuickBooks Desktop by doing some troubleshooting steps. This way, you can get back where you left off. 

Have you tried updating, uninstalling, and reinstalling the product as suggested by my colleagues above? If you have not yet done so, I urge you to do so. Ensure your QuickBooks Desktop version is 2022 R3 for the multi-user to work perfectly. To check the version, press F2 on your account homepage. 

If the issue persists after following the above solution, I recommend following the steps in this article regarding error code H202: How to fix Error H202 and H505.

Additionally, I've added this article that'll help you learn about the tasks that can be performed in single or multi-user mode: Features Available and Task you can Do With a Single or More Than One License.

Fill me in if you have additional questions about multi-user mode issues. I'm always here to help you. Keep safe, John.
