OS Windows 7 Ultimate 64 bit
Flex Builder 3 or Flash Builder 4
I'm getting the error message:
You do not have ASP.NET Development Server installed.
This error message appears whenever trying to set the Flex Server to:
Application Server Type: ASP.NET
Server: Use ASP.NET Development Server
It will not let me continue beyond this message.
The .NET Framework 2.0 is part of the Windows 7 OS.
Using Visual Studio 2010, I'm able to launch the ASP.NET Development Server, so I know that it does work and is installed.
How does Flex Builder locate the ASP.NET Development Server? Any ideas how to fix this?
I've just encountered the same problem and managed to fix it. The problem for me was Visual Studio 2010, it placed the ASP.NET development server files in C:\Program Files (x86)\Common Files\microsoft shared\DevServer\10.0. I copied the .exe and .config with '20' in the filename to the folder C:\Windows\Microsoft.NET\Framework\v2.0.50727. After copying the files I renamed them, I just removed the '20' from the filename. After these steps Flash Builder 4 was very happy to run my Flex application on the ASP.NET development server. This website contains the information I used.
I hope it will work for you too!
Thank you! That worked!
