the exeption throwing in my app code
Can you tell me if your exe is a console application? a window app will not run if being fired from a windows service
ASKER
it's a windows app, so if i change to console app it will work ?
ASKER
i don't need user interface,i can use console if it will work

ASKER
the Exeption is in access to windows registry keys, before sending the folder
a method should get the folder information from windows registry but can't do this
