How to Hack your Application Compatibility Toolkit 5.5 (ACT 5.5) Database to Locate 16-bit Files in your Application Inventory

(Wow, I’m doing a lot more posting today than normal. Things kind of piled up while I was on leave.)

There is a ton of activity going on in the world regarding Windows 7 deployments, and one of the hottest topics we’re finding is x64. People are very interested in moving to the 64-bit version of the operating system, but one obvious question is, will my applications be broken?

The next version of the Application Compatibility Toolkit, ACT 6.0, is scheduled to have far more robust x64 support. (It’s scheduled to support it at all, which is already a bonus.) But what about in the interim?

First of all, there is the Setup Analysis Tool. This will detect 16-bit binaries (probably a problem for 64-bit Windows, unless setup is detecting the bitness of the OS and dropping file appropriately) and driver installation (possibly a problem for 64-bit Windows, unless setup is detecting the bitness of the OS and dropping files appropriately). But this requires a fair amount of work to get configured and running, and it also means that you have to have the setup files. Depending on how managed your environment is, that may be a problem.

If you’re the sort that doesn’t mind undocumented secrets, I’ll let you in on one: ACT already collects the bitness of the files it finds in an inventory scan, it just doesn’t surface that in the UI today. So, how can you view this information? Why, hack the database of course. My SQL skills are so rusty these days I’m beyond embarrassed of what I crufted together, but here is a query I hacked up to display all of the files that are neither 32-bit (user mode 32-bit is probably OK) nor 64-bit (definitely OK) in your ACT database:


SELECT DISTINCT Applications.appName, Static_App_Properties.fileName, fileModuleType

FROM Static_App_Properties
INNER JOIN Application_Instance_Files
ON Static_App_Properties.identity_hash = Application_Instance_Files.filePropertyID
INNER JOIN Applications
ON Application_Instance_Files.appID = Applications.identity_hash

WHERE fileModuleType<>'32BIT' AND fileModuleType<>'64BIT' AND propertyType='File'

ORDER BY appName

The schema is, as always, undocumented and subject to change, but I have found this helpful in a few scenarios to quickly zero in on apps to specifically test on 64-bit when targeting a mixed environment. I suspect you’ll have to do less hacking with ACT 6.0.

  1. Thanks for posting again. Concerning your leave: Congratulations!

    Thank you for the sql statement, I read the article yesterday and made a customer happy today 🙂 We are analyzing their software ecosystem with ACT and this little piece of code came in very handy. If you have more of this "hacks", plz share them!

    is windows 7 compatible with my mac laptop

    @john otolo – I don’t know how old your Mac laptop is. If it’s one of these, probably not: If it’s of current vintage, then probably.

  4. nice tip, good one. any more news on ACT 6 release dates?
