.NET 4.5 was accidentally installed on an IIS node, .NET4 was uninstalled, as a result - it is impossible to use .NET 4 in CP for customers with webspaces on that node.

How to revert this?


  1. Remove .NET45 package from the node through POA PP in Hardware Nodes > <IIS node> > Packages tab

  2. Uninstall .NET 4.5 from the physical node if it still present through Windows Control Panel > Add/Remove programs,

  3. Run .NET cleanup tool on the physical node.

  4. Install packages ".NET4" and "ASP.NET4" through POA PP Hardware Nodes > <IIS node> > Packages tab.
