"The unit chosen is not supported."

Question

I get the msg: "The unit chosen is not supported." (Adobe error message)  when I attempt to retrieve a scanned image from the Xerox Scan Utility window that appears in Adobe Acrobat after I have scanned the document.
I can open MS Visio and retrieve that same image from Xerox Scan Utility window into Viso without any problem.
I used Adobe to initiate the scanning process by:
    - opening Adobe Acrobat
    - choosing "Create PDF"
    - choosing "from scanner"
    - choosing the Xerox WorkCenter scanner and responsing to the Select scanner option window
    - choosing "Options": Native Mode  (tried Memory Mode)
                                    Show Scanner's Native Interface  (tried Hide Scanner Native Interface in various combinations w/Native mode and Memory mode)
    - choosing "Append" to existing PDF
    - browsing and selecting the PDF
    - choosing "Make searchable"
    - choosing "Scan"
    - selecting the scanner when prompted
The went to Xerox scanner and scanned the document
Returned to Adobe
Got error when trying to retreive from Xerox Scan Utility window.
Using:  Windows XP Professional Version 2002 Service Pack 3
           Abobe Acrobat Professional 8.3.0  (after I had the problem, re-installed to make sure I had all the updates etc.)
           Xerox WorkCentre Scanner 5740 - on network
           TWAIN Driver downloaded from Xerox for that scanner
It appears that the last time I found anything related to this was 3 questions in 2002.  I saw no definitive solutions.  I had Xerox here to resolve and they could not.  Since it appears the Xerox part is workiong - the image is scanned and retrievable by Visio, then the issue seems to be with Adobe.  It also appears that Adobe is communicating with the Xerox since the Xerox Scan Utility Window displays in Adobe.
I called Adobe support and told them the problem.  They could not (would not) answer since they said 8.3.0 is not supported.  I asked if at least they could tell me what "The unit chosen is not supported." means - what is "unit".  I was told to look it up in help.adobe.com or google.com - both of which I had already done.
Does anyone know what the solution is ?  Thanks.

Answer 1

I respect that you are employed by MicroSoft, but the compatability center is not always accurate.  It indicated that Adobe Pro 8 was compatabile for both 32 bit and 63 bit - but it is not.  I have upgraded to Adobe Pro 9 Extended because Adobe says that this is compatable with 64 bit.  The Microsoft compatability center also says that v9 is compatable with 64 bit.  But it is Not.  I have upgraded Adobe to 9.3.0, and it is Still not working.  I now have $700 invested in Adobe software that is non-functional due to W7 64 bit.
So although users can check the compatability center - as I did prior to purchasing my new laptop - but it may not be accurate.
And yes, I have updated the compatability center to indicate that the information there is incorrect.
I have searched/googled everything that I can think of, and still nothing helps.  If you have a suggestion how to make this work, I am listening.
