I bought Acrobat DC Pro from Best Buy. I received a redemption code and located my serial number. When I try to install Acrobat I am told I am using and invalid serial number. Help!

No, it can't be transferred. Based on past experience you might be able to upgrade to DC 2017 and switch platform. You MUST go through Adobe sales, you can't do this online or through resellers.

I am attempting to install Adobe Pro XI onto a new mac computer and it keeps telling me that my serial number is invalid. Can anyone help? I've deactivated it on my old computer.

I bought Adobe Acrobat 9 Pro a few years ago from Challenger. I'm now migrating from my old laptop to the new laptop. When I tried to install the disk into the new laptop with serial no. It says that the serial no. is invalid. Please advise. Thank you.

Actually never heard of redemption code failing. I assume you are trying it from INSIDE your account details on http://www.adobe.com/, not when it asks for a serial number.... that's all I can think of.

Here are the Acrobat 2017 (permanent license) installer files:  

Download Acrobat 2017

You can’t use the 2015 product instead.

Ok, you may have downloaded the wrong installer, there are several similar ones. Is this package described as "Acrobat Pro 2017", as "Acrobat Pro 2015" or somethnig else? Mac or Windows?

I don't think I understand that best buy gave you a serial number yet you're trying to use a redemption code. Did you get both of these inside the same package?
