Not sure what is going on. Same old story, it works here. You don't have to do anything to set up for it. Just add the expression to the report.
First check Help/About and make sure you really have version 10.0.35.
Then go to tools/advanced/database commands. Type
? getversion(4)
followed by {Enter}. It should display 10.0.35.
I admit I never actually tested it in the report writer. But it works. See the attached example. I added getversion(4) to the northwest corner of the page. Uncompress into the REPORT folder inside where LOGic is installed.
Let me know!
