crystal reports server XI release 2 installation problem

Hello, everybody,

got 2 of crystal reports / server XI release 2 packages back in 2006

since then only crystal reports designer were used (great software) and it works fine.

but now trying install the server version included in the package, installation gives error

on the key what is supplied with in the package.

error message said "the product key code you entered is not valid"

is there are any time restriction on the official key codes?

can anyone, please, comment?

with best,

Janis Briedis
