Why there is an error in a wix project?

Question

I am using Wix toolset 3.8 and I try to create an msi project. While building I have an error like this one:

Severity    Code    Description Project File    Line
Error       '.', hexadecimal value 0x00, is an invalid character.   Analyzer    light.exe   0

Has anybody faced with such a problem? Any help will be appreciated! I am a beginner in this field... Here is the source code:

There is an open bug report in the WiX issue tracker that indicates that the error is related to your RTF file ending with a null character.

I would check whether your license.rtf ends with null end then truncate that character from the file (or create a new RTF file without null)
