Hello,
I'm having the same problem.
I'm using the ITR3 Utility for FY2017-18 released on 07-07-2018 (the PR2 version). It does not generate an XML, and I'm not able to submit directly online either. It saves a draft - thats all.
Clicking the SAVE button does nothing. It also does not seem to be showing errors. I searched the computer for "*.X M L" files ot see if it was saving something , but no fiels turned up that could have been saved by the utility.
I tried the May 2018 utility also, and that doesn;t work either.
Please help. How can I get the X M L file to upload? (I've had not ptoblem doing this any of the last 3 years with the Java Utility)
