MsiQueryProductState and INSTALLSTATE_ABSENT - dtieuf

Hi,

When a call to MsiQueryProductState returns INSTALLSTATE_ABSENT, MSDN
states that

Is there a way to (programmatically) find out for which user it is
installed ?

Thank you

Yes, it does exactly what I need. Unfortunately, I should have added
that I must target MSI v2 and this function requires v3+.

Thanks anyway

Try enumerating the subkeys of
HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\UserData --
per-machine installs are in the S-1-5-18 key, and per-user installs will be
in the subkey corresponding to the user's SID.  The Products subkey of each
SID subkey contains product codes in a slightly scrambled format.
