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.

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

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

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

I dont think you are right about that. Below is screenshot of my Visual C++ redistributables both x86 and x64, as you can see, none of these go to Wow6432Node
