▼ Check the Windows System Information app

If your software hangs on the splash screen after login, it could be an issue with the Windows System Information app.

In the Windows search bar enter system information, then click System Information

If this window populates, as shown in the image below - there's no issue with the System Information App. Follow the steps on the Reset Microsoft.NET Frameworks section.

If the System Information window is blank or displays an error message, this indicates an issue. To resolve this:

In the Windows search bar, enter cmd then right-click Command Prompt and click Run as administrator.
Type net stop winmgmt thenpress Enter
To continue press Y if asked,then press Enter.

▼ Unable to stop winmgmt?

If you're unable to stop winmgmt:

Hold down Ctrl, Alt and Delete on the keyboard and select Task Manager.
Click the Services tab and locate Windows Management Instrumentation, right-click and click Stop.

Type winmgmt /resetrepository then press Enter.

This will report that the repository has been reset.

Type net start winmgmt, press Enter, then close the Command Prompt.

This can report that the WMI Service has already started, this is normal.

Open Sage 50 Accounts and log in to the company. If the issue persists, continue to Step 6.
