FinalBuilder6 with .Net4.0

I would like to create a build of my .net4.0 projects using FinalBuilder6.0.But in the 'MSBuild' action I do not find 'v4.0' and when I try to run my project with 'v3.5' setting for MSBuild I get this error message.

'Project file contains ToolsVersion="4.0", which is not supported by this version of MSBuild. Treating the project as if it had ToolsVersion="3.5".'
 

Could someone please help me in resolving this? I know that FinalBuilder7.0 has the option to run .net4.0,but in my company is using FinalBuilder6 at the moment.

 

Thanks.

 

 

Make sure you have the most recent FB6 build installed, it does support .net 4.0.

Thanks.
