I needed to change the config.xml for an Office (OneNote) 2010 deployment. After changing the config file I tested the silent installation but the installer couldn’t handle my newly created config.xml file.
All my xml tags where closed like it should, I couldn’t find any syntax error. But then I remembered something learned at school (it’s been 10 years!); opening an XML file in Internet Explorer to verify the syntax!
I used the Dutch word “geïnstalleerd”. After removing the special character (changed to “geinstalleerd)”, the Office 2010 installation was successful.
