When I attempt to install the ERP 2021 R1 Update 6 version from the downloaded AcumaticaERPInstall.msi file, I receive the error listed in the title above. I also receve the same error when attempting to install the ERP 2020 R2 Update 11 version.
I have reviewed the “Сan’t get your IIS version from the registry. Probably you don’t have IIS?” error resolution, but I cannot duplicate it. My registry does not have the key: Computer\HKEY_LOCAL_MACHINE\SOFTWAREMicrosoft\InetStp
Please advise. Thanx.

In Windows go to Control Panel\All Control Panel Items\Programs and Features, and then click Turn Windows features on or off on the left pane.
Enable the following:
Web Management Tools > IIS Management Console
World Wide Web Services > Application Development Features > .NET Extensibility
World Wide Web Services > Application Development Features > ASP.NET
World Wide Web Services > Application Development Features > ISAPI Extensions
World Wide Web Services > Application Development Features > ISAPI Filters
World Wide Web Services > Common HTTP Features > Default Document
World Wide Web Services > Common HTTP Features > Static Content
World Wide Web Services > Performance Features > Dynamic Content Compression
World Wide Web Services > Performance Features > Static Content Compression
World Wide Web Services > Security > Request Filtering
