Hi!

I'm trying to make admin installation with non-admin user priviliges. As I
understand, admin installation should simply unpack the files. However, the
installation fails with the message (see below) from MSI log. The user
doesn't have Write permissions to machine-wide registry (as usual).

So why it writes registry?

Investigating further under RegMon shows that it opens HKLM\Software\Classes
with requested access 0x2001F (READ_CONTROL, KEY_NOTIFY, KEY_ENUM_SUBKEYS,
KEY_CREATE_SUBKEY, KEY_SET_VAL, KEY_QUERY_VAL). However, even with
appropriate permsissions it doesn't write anything when I make another run
under admin account. So the requested open access mask seems to be
excessive.

So is it normal behavior not allowing non-admins to perform administrative
installations or something went wrong ?

Regards,
Aleksey Karyakin
