Hi Markus,
This did not work for me as AO 2.2 SP02 still requires a .NET 4.5 or higher. The uninstall of .NET 4.6.1 resulted in same failed installation requiring .NET 4.5 or higher. SAP Support reiterated that the permanent code fix for this issue will be in SP03 that is supposed to be released next week (first week of May).
