If you get the dialog below when starting dwdatarp.exe or any other tool, this means that the tool was developed with .NET Framework 3.5 (or even earlier) and it requires the appropriate .NET Framework to run. You may overcome this dialog by installing .NET Framework 3.5 on the computer.
But sometimes you may not want to install an old version of .NET Framework, especially on Windows servers.
Most of the time, there may be a newer .NET Framework (v4.0/4.5) installed on the server. To verify, check if under C:\Windows\Microsoft.NET\Framework or C:\Windows\Microsoft.NET\Framework64 you have a folder that starts with “v4.”. If yes, then you have a shortcut to run your tool, without installing an old version of .NET Framework.
Simply, create a blank text file in the same place with your exe file. Name the text file the same as your exe file and append “.config”. For example, in our case the text file should be named as dwdatarp.exe.config.
Now, paste the following lines into this text file and close it.
That’s all. Now run the tool again. It should start as expected.
