Invalid Serial Number for Adobe Acrobat XI Pro?

Had to reformat Hard Drive with Windows 7 Pro.  Tried to reinstall Adobe Acrobat XI Pro by going to my account and obtaining serial number.  Then downloaded AcrobatPro_11_Web_WWMUI.exe to install. 

When prompted to enter serial number, I entered serial number from my account history.  Message indicated that the serial number was invalid.  "This is not a valid serial number.  Tried entering serial number (24 numeric) with both hyphens and no hyphens.  No go! 

Downloaded Adobe Acrobat Cleaner from previous suggestion and ran that, rebooted and still - error message received regarding invalid serial number. 

What additional steps, if any, can be done to reinstall XI Pro?

    Install it as a Trial. Then, under the "Help" menu, select "Repair Acrobat Installation." It will tell you it is in trial mode and how many days are left. From here, you may click the button to license the product.  You will be prompted to Sign In to the adobe Web site and enter your serial number.  It seems to consistently work if entered this way.

    Upgrade products are the complete, full thing. The only difference is that you must own the older version. If you never owned an older version, or didn't keep the serial number, you seem to be stuck.

    I think it is asking for a "qualifying product"? That means you are installing an upgrade. The serial is valid but now you must prove eligibility by giving the serial number for one of the older (qualifying) products.

    I’m installing a complete new version, not an upgrade. I have completely different products and serial numbers.

    your license is for an upgrade version.

    when starting your installation you're prompted for your xi serial number.  when the installer fails to find a qualifying product (ie, previous version) installed, you will be presented with a dropdown of possible qualifying products.  select the one you own.  you will then be asked to enter the qualifying products serial number.

    enter the correct number at the correct time and installation will proceed.

    How is this a correct answer.  I am in the same boat as @robc71162312 !.  Downloaded Acrobat XI from the Adobe website, used the serial number provided in my account settings, and I get the same error.

    Presumably it was a correct answer because, for the original poster, one of these five solutions solved their problem.
