Also try aspnet regiis -u then aspnet regiis -i on below path  C  Windows Microsoft NET Framework v4 0 30319    Now restart the IIS and check  Hope this will help

Each individual Web App under an IIS Web Site can use a different App Pool   Verify the App Pool assigned to your app  not just the root site per your pictures  is  NET 4 0 compatible    Expand Default Web Site Right click on ProjectPALS  choose  Manage Application  then  Advanced     Observe the  Application Pool  your app is running as under the site Change to another App Pool if neccessary

This typically happens when you have an attribute of targetFramework  quot 4 0 quot  in the web config but the App Pool is set to run ASP NET 2 0  The targetFramework attribute is entirely unrecognized by ASP NET 2 0 - so changing it to 2 0 won t have the desired effect  Contact Support   Your Administrator and have the AppPool switched to 4 0  You could also remove the attribute entirely  however if your site was coded with the 4 0 Framework  then I m sure something else will cause an error as well   Unrecognized attribute   39 targetFramework  39   Note that attribute names are case-sensitive

Have you tried the aspnet regiis tool to register  Net 4 0 for IIS  You can check more at msdn

My problem was solved that way   Your username is probably restricted  You must grant full access to the user    Right Click on Project and select Properties Click on Tab Security Click Edit button     Found Current User and Permission for User Allow Full Control

If your application is 32 bit  and you want to deploy in a 64 bit machine  You need to set  Enable 32 Bit Applications  property to  True  in the application pool - advanced settings

Try this  instead of selecting your websete s Application Pool to DefaultAppPool  select ASP NET v4 0  Select your website in IIS    Basic Settings    Application Pool    Select ASP NET v4 0  and you will be good to go  Hope it helps

You could be using the 32 bit version  so you should prob try at the command line from the Framework  not Framework64  folder   IE Did you try it from  C  Windows Microsoft NET Framework v4 0 30319 rather than the 64 version  If you ref 32 bit libs you can be forced to 32 bit version  some other reasons as well if I recall   Is your site a child of another site in IIS    For more details on this  since it applies to various types of apps running on  NET  see Scott s post at   32-bit and 64-bit confusion around x86 and x64 and the  NET Framework and CLR

How are you running the application   Are you just hitting the website or are you building and running from within Visual Studio   If you are building and running you may want to tell it to use the local IIS web server   This would make sure it is using the App Pool you have set up to run with v4 0 integrated   I am guessing that it is using the Visual Studio Development Server when running   This server is probably trying to run with the 2 0 framework   This then causes your error to be thrown   Edit   To note  I normally just build my website application and then I attach to process w3wp when I want to debug   I do not use the publishing tool   Of course this means my local working directory is within the web root

Make sure that you are building your web app as  Any CPU   Right click your web project --  Properties --  Build --  and look for the  Platform Target   Choose  Any CPU  or play around with it   Hope this helps
