[knapshots]

Guys, we got the .crt and .key files from nokia
and also the uid for our app

we added the uid using target.uid3 thing in the pro file
and vendor name thing as well using the packageheader specification in the project file
we also made it a point to replace the default uid in the pkg file with 0x22....F thing
and finally signed it using signsis after creating the smart installer packaged version

we get some umm strange errors though...

1. Appsize and vendorname are unknown
2. we get this message "Unable to install a protected application from an unknown supplier"

Is this really a Qt related issue? or more a nokia (symbian) related issue? Is perhaps forum nokia the better place to ask?
