Errors on updates

Experiencing technical issues while revamping software for months could make you wonder about its cause, and I'm here to share the possible causes and guide you on how to fix them to help you update the program successfully, @wilcoqb. 

Your users might experience Error 12002 due to issues with internet connectivity and security. QuickBooks may have trouble connecting to the internet, or an antivirus or firewall program is blocking the update process. To prevent this, let's check your connection and settings. Since the system uses Internet Explorer to access the net, it should be set as the default browser. Next, download and run the TLS 1.2 Utility to confirm that you can access a secure web review of your browser settings.

QuickBooks offers a Tool Hub for setting up and repairing network security and personal firewalls. If you prefer manual configuration, follow these steps:

1. Open the Windows Start menu.
2. Type "Windows Firewall" in the search box and launch Windows Firewall.
3. Navigate to Advanced Settings.
4. Right-click on Inbound Rules, then click New Rule.
5. Choose Port and then Next to proceed.
6. Ensure that TCP is the chosen option.
7. Enter the required specific ports for your QuickBooks year version in the Specific local ports field.

For a more detailed procedure, refer directly to Step 3 of this link for guidance. 

When users access the QuickBooks company file remotely, encounter server overload, or use a corrupted company file, they may encounter Error 503. It can also be due to poor internet connectivity and firewalls, similar to the first prompt. Therefore, to troubleshoot this issue, here are the steps to follow:

1. Review your internet connectivity.
2. Turn off the Firewall or Security Software.
3. Restart the QuickBooks servers and workstations.
4. Recover and repair your QuickBooks installation.

Please note that the first two guides are the same as the reference provided in the troubleshooting for error 12002.

Thanks I will take a look at some of this. Internet Explorer is a big no no... Our security team will absolutely NOT allow internet explorer to be the default for very obvious security reasons. That is banned within our organization. And quite frankly I do have some users without issues. In our organization group policies manage all of the computers and they are installed by image so it makes no sense that some users can and some cannot update.

I asked support yesterday if they could let me know the server address (URL etc) where QB gets updates so that we could add it to the firewall as a "safe" option, but support was not able to tell me that.
