Product Code - Adobe Reader 10 vs 10.0.1

Question

Hi,
We have a deployment solution (and are according licensing) for pushing updates of certain applications, including Adobe Reader to our desktop farm. This solution uses product codes to identify changes between the currently installed version and new versions being shipped.
This has worked pretty well in the past, but it seems like the product code for Reader X and Reader 10.0.1 are the same. Based on the Microsoft guide lines for Product Codes, it seems like a point release with significant security updates should qualify for a new product code. Is this us doing it wrong, or was there a deliberate decision to not update the product code for this release?

Answer 1

The difference in file size does not matter much. That might be different becuase they are two different deliverables.
As far as understanding which version is installed , I think you can try out following :
1.  There is a KB article by Adobe on this , see if it help you :  http://kb2.adobe.com/cps/837/cpsid_83709/attachments/Acrobat_Enterprise_Administration.pdf
2.  You can also see "Version" /"Display Version" entry in  [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{AC76BA86-1033-F4 00-7760-000000000005  or the product code for Reader}].
Version Entry reads : a000001 which stands for 10.0.1 in decimal and display version directly reads 10.0.1.
Seems to be reliable to me.
