Where are product uninstall keys located in the Registry under Windows 7 x64?

Question

I need to look up the install location of a product in the registry, based on the GUID product code. Under Win XP the keys of products installed were located at

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

For example, if I had the GUID {034759DA-E21A-4795-BFB3-C66D17FAD183} I could look up

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{034759DA-E21A-4795-BFB3-C66D17FAD183}

and there would be a value containing the install location for the product.

However, the Registry doesn't appear to follow this same setup in Win 7 x64. Does anyone know how I can do what I did in XP, but in Windows 7? Thanks.

Solution 1

Just checked my Win7 x64 system and the registry shows an InstallLocation key for most of the entries.

Solution 2

For 32-bit applications installed onto 64-bit Operating System, browse to the following

HKLM\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

But are the entries listed as GUIDs located under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall?

Yes they are. I just looked at your original post again and you don't have a "\" between \Uninstall and the GUID. Could just be a typo here, but you'll definitely need that in the registry search.

That was just a typo in the post. Hmm, the product I'm working with doesn't seem to create the proper entry under Uninstall in Win7 x64. I just installed Java, and it had the keys where I expected them. Thanks for the input.

It depends on the bit-edness of the installer - not of the installed files (which can be mixed). Effectively the win x64 control panel uninstall tool looks up both locations.
