I have a brand new shrink wrapped DVD version of Adobe Acrobat XI pro I installed on a Windows 8.1 (64 bit) desktop machine.

Adobe acrobat will not update I get (Error 1328).

When I entered the serial number to register the product on Adobe.com, i get a message saying "enter valid serial number."

WTF, it is a valid serial number for a product I paid for.

What is the problem?

HI,

Did you ever get any satisfaction or explanation about your installation issue?

I've got the same problem. new, sealed in box Adobe Acrobat XI Pro that will not install under Windows 10. I keep getting "unable to connect to the internet" errors. For the longest time, I'd get put on hold or in a chat que while trying to address this issue with Adobe. Finally had time to kill this morning and got through via chat. After much running around, I got the :sorry, this is an invalid serial number, please address the issue with the retailer" excuse.

The software is open; the retailer will not take it back. They claim this is an known Adobe registration problem.

Would be interested if you found a solution.

Acrobat XI is an old and unsupported version. Why did you purchase it now? Anyway, if Adobe is saying it's not valid, it's not valid.

Contact the retailer and demand a refund.

Did you actually read everything I wrote?

You assume I don't know XI is not the current version. On the contrary, I do. But, why should I buy a new version when XI (a) meets all my needs and (b) is, according to Adobe, Windows 10 compatible?

I have licenses for three (3) copies of XI (all from the same retailer), but this one somehow will not validate. All came in shrinkwrapped retail packages.

If this one copy is truly "not valid" then let Adobe explain to me exactly what is "not valid" about this copy - was it already registered to another end user? Is it a pirated copy? Or, is refusing to allow registration of an old but valid copy of an Adobe product just a marketing method to get me to buy an upgrade I don't actually need? [Been there before with other software vendors.]

If the copy is truly bad for one or more reasons, I need written proof from Adobe with an exact explanation (not some generic "not valid" excuse) so I can go after the retailer in court. Remember - the retailer has a very good case (of three copies I bought from them, only one copy will not register). I need solid, detailed descriptive letter/message from Adobe to explain why only one of three copies I purchased is "not valid." Last, I've had multiple discussions with the retailer and its managers, who consistently claim that all copies of Adobe products it sells were obtained through legal distribution channels from a licensed Adobe distributor.

A word of advice - next time read the entire message you're replying to, understand it, then and only then hit REPLY.

Yes, I am using the 24 digit serial number in 6 groups of 4.

at this point adobe will never get so much as a penny from me again.  I do not have time for this nonsense.

I have a real business to run.
