Picking up this thread again, as I have a similar problem...

I am also trying to convert a batch of Word files with Acrobat 6 Pro,
both via Word/Open/Tools/Print (i.e. using Distiller, or what is now
called the Adobe PDF printer), or right-clicking on a batch of files
in Explorer, and if I select more than 25, Adobe will not convert them
all.

I have made sure all the "Proppt for filename" and "Show results in
Acrobat" boxes are unticked, but still, it looks like it's impossible
to convert more than a certain amount.

When I do the right-click procedure on more than 25 files, the process
won't even start, and I get a n error message that says that "Acrobat
Elements.exe" could not be found.

Can anybody help? :(

Thanks in advance
Andy
