Ok - so I get a report printing to html using the vfp 9 report engine, thus:

loListener = .NULL.
do (_reportoutput) with 5, loListener
loListener.TargetFileName = htmlfolder+htmlfile 
loListener.QuietMode = .T.
report form xyz.frx object loListener

It works perfectly on the dev machine, but not on the client machine. I find that it requires 'extras' to make it work.
According to MSDN there are options:
1. Include this line in config.fpw: _REPORTBUILDER=path\ReportBuilder.App (obviously with my path and without the original angle brackets around 'path' in this example (this site will not let me include them))
That doesn't work. Yes - ReportBuilder.App is in that path.
2. Add this next stuff into your main.prg to build the system into your exe: (as copied and pasted from their web page)

* Ensure the report builder source is pulled into the project:
EXTERNAL PROCEDURE frxbuilder.prg
* Set the system variable to use the local source version:
_REPORTBUILDER = "frxbuilder.prg"
:

Compiler doesn't know what the ":" is, and won't compile it. So I comment it out, and it still doesn't work.

I have recreated the Home() path on the client machine, and included anything and everything relating to reports in that, and still nothing...

Please advise what else I can do to get it going.

So many thanks!
