I think I blew up my Web Platform Installer. I was trying to add Azure Powershell cmdlets but had some internet connectivity issues while the download was happening so I decided to cancel the install. The cancel appeared to stall so I pulled up task manager and hit 'end task' on the Web Platform Installer. Now I am unable to install the Powershell cmdlets because "Another installation is already in progress. Complete that installation before proceeding with this installation".
How do you fix this without doing a clean Windows install?
Edit: apparently this error is only happening for the Azure Powershell cmdlets. I was successfully able to install the xplat-cli (even though I don't need it). Just wanted to see if the WPI was completely borked or not.
