I downloaded and installed inventor 2015 professional (student version). When I press activate and choose the option "connect now and activate" it says my serial number is invalid which it isn't. I am using the same serial number you guys sent me via email. I sent a ticket to costumer support but they told me that my serial number is invalid...that's what I was contacting them for and they reply to me with the same error.
Hi Yacoub,
I was able to pull up your account using the email address on file, however I am not seeing any Serial Numbers or Products. Please try downloading another Product and check if you still have the same error.
If so, please register another account using a different email address.
