During an installation with AutoSPInstaller on my development machine I ran into a strange issue. I got the following error: System.IO.FileNotFoundException: Could not load file or assembly ‘Microsoft.IIS.PowerShell.Framework’ or one of its dependencies I haven’t found any other people having the same problem with the AutoSPInstaller, but I found a similar report on another forum: help.octopusdeploy.com. Maybe I am the only one who gets this error in AutoSPInstaller, if not it can be useful to write the solution down.
