Load the exe into a directory by itself.
There is no setup and it doesnt touch the registry

Start telescope and connect serial comms
Start App and let it detect the scope
( it will also detect scopes already in download mode )

Select page range required
( note, the boxes operate in hex )
Normal code starts at page x02
but you can start at x00 if required

For a 497 the max page is x1F
For a GPS the max page is x6F  // LX600 and 850 as well
For a RCX the max page is x7F

There is also an option to peek the low ram
If this is selected the dump will start with x0000-x7FFF
followed by the selected page range
If the "low only" is selected, only the low ram will be dumped
irrespective of whats in the page limit edits.

Hit go and you will get several warnings.
If the scope is patched for peeking, 
you will get two options "Peek" or "download". 
99% of the time, download should be selected.
Hit go and it will make a file named in accordance with
the scope type connected and the range selected.

As the file is a binary one, zip it before emailing anywhere
as some nasty control chars groups could accidentally occur :-)
