I am trying to detect if C++ Redistributable 2012 update 3 is installed on machine.... I am currently doing check for 2008 through registry search and using guid, but I do not know guid for 2012 update 3... Does anybody know how to detect it?
I also found this link but it`s not exactly for update 3 and I do not know right numbers which I should to check...
Thanks

You can figure this out yourself for any installer: use a pc that doesn't yet have the product installed, start procomon, add a filter so that includes only info from the installer process (something like command line contains vcRedist should be sufficient) and start the installer. After it finishes, examine which registry keys it wrote.
For VS2102 the interesting stuff will be here:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DevDiv\vc\Servicing\11.0
(which is by the way also answered in the question you link to)
edit in addition to the above, you could also check
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\5C4834679ACBC703A9CADF44632686A6
or
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{764384C5-BCA9-307C-9AAC-FD443662686A}
(note both are for the x64 redistributable), that's how eg Installshield's prerequisites perform the check.
