When attempting to launch SmartObject Service Tester, the following error is shown:
When you edit C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Config\machine.config with a text editor, and on the first line, the following xml declaration is seen:
If you do not see the same encoding, then check if your encoding is set to something other than "UTF-8".
C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Config\machine.config should be using the "UTF-8" encoding. If you are seeing any other encoding, then change it back to "UTF-8", and save the machine.config. The first line of the machine.config should look like this when you are done:
<?xml version="1.0" encoding="UTF-8"?>
