I haven't dug under the code details in EAL, so I'm relying on what I can
tell from the Framework documentation...
I'm going to suggest that you comment out the line that sets the 'category'
parameter to a string. The API allows a category to be written to the event
log, but only as an integer, and only if you have already mapped category
strings to these integers. As far as I can tell, the Framework has no way
to do this. It has to be done through registry updates. I do not know if
the EAL does this updating... but your installer does not.
Therefore, try commenting out the following line:
> log.Category = "General";
and see if that helps.
