running installer on win 7 (previous installs of octopus have worked on this pc)
I get this message
Octopus
Error: Error when attempting to execute C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe: The specified executable is not a valid application for this OS platform.
OK
I click OK and the install stalls saying it is looking for .Net 4.0
