Issue Error while changing .net version

[qualispace]

I am facing a problem in changing the .net version off a few virtual directories in one of the Plesk servers. The Plesk panel throws an error stating the following

System.Exception: .NET Frameword version 2.0 not found.
at ASPNETConfigure.ASPNETConfiguration.normalizeFrameworkVer(Version ver)
at ASPNETConfigure.ASPNETIISConfiguration.set_FrameworkVersion(Version value)
at ASPNETConfigure.ASPNETCfgApp.run(String[] args)
at ASPNETConfigure.ASPNETCfgApp.Main(String[] args)

Please note the spelling of Framework. It shows Frameword. This happens while trying to change the .net version to 3.5. While setting it to 4.5, there is no error. When I manually change the application pool for the virtual directories in the server, the .net version automatically gets set to 3.5 in Plesk. I am unable to find the cause of the error. Can someone help?

It seems to be a bug with the current Plesk version as we are facing similar issues in other servers too.
