if we go to install any one version, we should Check 'Web Service Extension' option "prohibit or Allowed"
For Example If we install v2.0 in IIS, we should do prohibit v4.0...
If we install v1.1 in IIS, we should do prohibit v4.0 and v2.0 option also.
For Quick Reference
For 32bit Version To v1.1: %SystemRoot%\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i -enable
%SystemRoot%\Microsoft.NET\Framework\v1.1.4322\Aspnet_regiis -s W3SVC/1/ROOT/>"Type ur Virtual Directory Name here"
v2.0.50727 / v3.5 --No need to install 3.5 framework,bcz v2.0.50727 also support for v2.0
