Adobe Flash Player Enterprise Install Issue

Question

Couple months ago we deployed Adobe Flash Player 10.0.45.2 (ActiveX) to our enterprise.  Recently, our users have been calling the help desk stating that when they visit sites that have flash content, it asks them to install flash (however flash player is already installed on their computers).  I'm in charge of packaging and deploying at our company and this is the first time I've seen these after heading up multiple flash updates.  I've recently upgraded a few of our training rooms to Adobe Flash Player 10.1.82.76 and so far have not been able to replicate this issue with the new version. My concern is that after we deploy this new version to our whole enterprise, the issue will appear again.  So my question is, has anyone else seen this issue and/or know why it's occuring?
Windows XP SP3 (32-bit)
Internet Explorer 7.0.5730.13 (32-bit)
Adobe Flash Player 10.1.82.76 ActiveX

Answer 1

I think we're getting closer to a root cause!  I'm comparing two computers (we'll call them Computer A and Computer B).  They are identical in every way expect Computer A has a working version of Adobe Flash Player 10.0.45.2 and Computer B does not.
Computer A: Windows XP SP3, IE7, Adobe Flash Player 10.0.45.2 (flash working)
Tools > Internet Options > Programs > Manage Add-Ons
Add-Ons that have been used by Internet Explorer: Shockwave Flash Object enabled
Add-Ons currently loaded in Internet Explorer: Shockwave Flash Object enabled
Add-Ons that run without requiring permissions: Shockwave ActiveX Control enabled & Shockwave Flash Object enabled
