Did you check the inside of the back cover?
Yea, all the normal places

. Installation did not ask for one making me think one was not included. However it wouldn't be the first time someone has forgot to include a product key by mistake. What's strange is the developers are asking for a securom key to validate for developer upgrade. Is a securom key the same as a product key?
edit - I just noticed I'm probably not in the right thread for my game version - srry gents.
Email Larian (support@larian.com) with the SecuROM key for the PC retail version of D2:ED or DKS to get a voucher for D2:DC from the Larian Vault.
