This error is typically raised under non-English regional settings. When the hardware template editor is trying to parse some floating point values in the xml file, it runs into problems because of the decimal symbol being "," instead of "."
- In your "Regional and language Options", change the decimal symbol separator to a full stop "." Please make sure to set this setting for the current user as well as the default/system account.
- If the above does not work, try to set the language to English for your current user and system account.
