The type initializer for 'System.Management.Automation.Tracing.PSEtwLog' threw an exception.

This post describes how to fix: The type initializer for 'System.Management.Automation.Tracing.PSEtwLog' threw an exception.

Background

I recently installed XIA Configuration on Windows Server 2008 and wanted to scan a Microsoft Azure tenant.  In order to do so, I first had to install the Azure PowerShell cmdlets.  This required WMF 5.0 which I downloaded and installed.

Error

I then tried to open PowerShell but it immediately closed.  When I tried to open PowerShell in a command prompt, I could see the error was

'The type initializer for 'System.Management.Automation.Tracing.PSEtwLog' threw an exception.'

Fix

After doing some research, I discovered I also needed to install .NET Framework 4.5.  PowerShell then opened successfully and I was able to install the Azure PowerShell cmdlets and run the scan.

Video

You can see this fix in the following video PowerShell does not open on Windows Server 2008:

This post describes how to fix the error "This app will now restart to free up more memory" which can occur when using apps such as Netflix on an LG TV after just a few minutes of use. Resolution To resolve the issue, unplug the TV then press the on/off button for 10 seconds.  Wait a further 20 seconds then plug the TV back in and turn it back on. Apps should now run without the error. Edit: The on/off button on my LG TV is directly under the standby light on the bottom of the TV. Edit: I didn't have to do this myself but one person who has left a comment said that clearing all browsing data worked for them.  I have written a post explaining how to do this: LG TV Clear All Browsing History Data . Edit: A few other people have also suggested turning off quick start in settings (and if it's already off, turn it on then off again).  I have written a post explaining how to do this: LG TV turn off Quick Start in settings Related Posts -  LG TV delete/rem...
