Hi, I have a problem about this, I am always taking the same message "Object reference not set to an instance of an object. Additional info: Project XML file is not formatted properly." Do you have any information about this problem? I tried too much option but always coming to the same message. Can you help me, please?

Hi necat.

Firstly, welcome to the forum.

From memory- I had this before; and I fixed it by simply upgrading the cmpare tool.

What version are you using? The most recent version is v7.10.00

necat there are other ways to compare. If the compare tool is not working for you - I know there are compare issues with rslogix V24 and up. I wish from time to time that rslogix emulate is fixed for higher revisions.

Other methods to work around:

  • save the files as L5K and do a compare with notepad++ - it does a decent job 
  • print the two files out as a pdf (generate a report) and do a diffpdf (available on portable apps) --> it shows visually what code differences are there.

Hope this helps as well.
