Windows Live Mail Hanging

We have a client that has been using Windows Live Mail 2012 on a WIndows 7 Pro computer.  WLM will start but freezes when trying to read messages.  If the process is killed in Task Manager, the program will not restart until the system is rebooted.  Searching for a solution, most sites recommend removing and reinstalling the software but most suggestions were dated prior to 2017.  But this is not possible because the installer tries to connect to Microsoft for updates and fails.

When the program fails, we see these items when selecting details in Task Manager:
Problem Event Name:  AppHangB1
Hang signature:  eca7
Hang type: 2305

The event viewer shows Event ID:  1530 with message "Windows detected your registry file is still in use by other applications or services.  The file will be unloaded now..."

The client is considering moving to Outlook but prefers WLM.  

Our questions:
Has anyone successfully resolved this or similar issues with WLM?
Could the issue be OS related instead of WLM?
Can anyone recommend a free mail client that would be a replacement for WLM?  They did not like Thunderbird.  Any experience with Evolution or SeaMonkey email clients?

Thanks for any suggestions or trouble shooting assistance.

I had this running on Windows 7 when I used Windows 7 a while back.

1. Try SFC. Open an admin command prompt and run SFC /SCANNOW.  Allow to complete, close out, restart and test.

2. WLM does not go forward.   Ask your client to recognize this, convert the file to Outlook and a PST file and then move forward to Windows 10 and an Office Subscription with ease.
