Error when upgrading from Acrobat Standard X to Pro X

[RKodner1]

We are installing retail Acrobat Pro X upgrades over OEM Acrobat Standard X (that came on Dell Optiplex 390 systems). We're getting an error message that says "Setup has detected you already have a more functional product installed. Setup will now terminate." That of course, makes no sense. How do we resolve this so we can install these upgrades? Thanks.

Further, it looks like we're not the only ones having this kind of issue: http://forums.adobe.com/message/4110223 - for whatever it's worth.

Hi,

I would like to know what is the version of Acrobat Standard on your Dell Optiplex system. Depending on this I can suggest a workaround to you.

Thanks,

Vinod
