Unrecognized attribute 'targetFramework'. Note > that attribute names are case-sensitive

I try to publish a web application from my VS2012 to a remote computer. I published the files but when I try to open the website, I get this error: Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive. Source Error: ``` Line 41: Line 42: <compilation targetFramework="4.0" /> Line 43: <httpRuntime targetFramework="4.0" /> Line 44: <authentication mode="Forms"> Line 45: <forms loginUrl="~/" timeout="2880" /> ``` (line 43 is in red ) On the remote computer : * IIS7 is installed (and also IIS6, I think) * ASP.NET 4.0 is installed * "aspnet_regiis -ir" > installed successfully * IIS7 > Application Pools > ASP.NET 4.0 > poining to ".NET Framework v4.0.30319" * IIS7 > my web application > "ASP.NET 4.0" (Integrated) is chosen. I don't know if it 's important but server's windows is Widows Server 2008 RT Enterprise 64-bit and my computer is windows 7 32-bit. Nothing helped...
