Version Information: Microsoft .NET Framework

Solution

For my case, the reason hit above error is because.NET Framework was installed before IIS server. To solve the problem, register .NET framework to IIS will do.How to do that? (please be aware that the sample using for.NET Framework V1.0)

Steps

1. Click on Start -> Run 

2. Type in cmd and click OK

3. Command prompt screen will appear. go to"C:\Windows\Microsoft.NET\Framework\v2.0.50727" folder by using command cd C:\Windows\Microsoft.NET\Framework\v2.0.50727 and hit enter. Please refer screen below: 

4. Type in aspnet_regiis -i and hit enter. 

5. Screen below will be shown and dotnet user installed.

aspnet_regiis -i,alternatively you can copy and paste this command into windows command prompt

%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i
