i'l try to understand the call of sentinel.dll to jump it
then the setup's program 'll be fully optional but noway to do this

next the second request is
that the geoport check everytime if the dongle is here
some's got an idea ?

I don't know if that helps . I have undongled one one programm protected with
sentinel shell. So how sentinel shell works i think :

It decrypt itself using some data stored in the dongle , so see if your's dll
is not encrypted.

In any case you can see what exported functions setup call from dll, an write
own dll ( for ex. in Delphi ) with the same function names but returnig allways
correct value expecting by setup shield

Sorry for corrupted language and best wishes.

P.S. whar u are undongling ?

Attached Setup.exe is not enought, it looks for setup.Lst and fails

here there is the rest of the setup prog
thank for all
