Installing 6.45 with default settings. The program runs only as I log in as administrator. tried it on a XP and a Vista machine.
Logging in as a user without full rights and it doesn't run.
Looks as if it doesn't run as a service?
Am I right that you need full rights to run Boinc (CUDA), not a thing you normally want to do...

First off, when you want to use CUDA, you must not install it as a service (not Protected Application Execution). (the default installation for 6.4 is not as a service)

Second, if you want other users to run and handle BOINC, you must check the option "Allow other users on this computer to control BOINC".

First That I did.
Second as well.
But BOINC only runs when I login as administrator.
Even as I checked (default) all users. (On XP and Vista machine) All users means users with Administrator rights?

As far as I know, it shouldn't.

Could you do me a favor and check what the ENABLEUSEBYALLUSERS key is set to in HKEY_LOCAL_MACHINE\SOFTWARE\Space Sciences Laboratory, U.C. Berkeley\BOINC Setup on your admin account and any of the user accounts?

While you're there, check what SETUPTYPE is set to as well.

Register keys:

LAUNCHPROGRAM 1
MIGRATION TRUE

RETURN_VALIDATEINSTALL 1

SETUPTYPE Shared

What I noticed is that in C:\ProgramData\BOINC\ the rights are set to read execute
I set the rights to all (except special) for the user without administrator rights
The rights in the program map appear ok but I set them to all for the user without administrator.

Now the boinc icon appears in the tray but as reconnnection.

Checked boinc.exe/boincmgr.exe/boinctray.exe all have full rights for the user

More suggestions?

Restarted again and it seems to work.
The installer seems to fail in seting the rights for the data map correctly.

In XP:
C:\Documents and Settings\All Users\Application Data\BOINC
Explorer right mouse on BOINC map, properties (eigenschappen)-> security (beveiliging)->add button (toevoegen).
add user (gebruiker) (press the check button) add rights: change (wijzigen) and write (schrijven).

C:\Program Files\BOINC the same way as above: add user (gebruiker) rights should be ok read execute (lezen uitvoeren), display map (map weergeven), read (lezen)

Och verrek, je bent een Nederlander. Had ik niet eens naar gekeken. ;-)

Ik zal wel doorgeven aan de maker van de BOINC Installer dat er problemen zijn met het geven van de correcte permissies. Nog meer voor zijn 'todo' lijstje. :-)

Vraagje: is dit met een Nederlandstalige Windows XP? zou niet uit moeten maken, maar toch.

Inderdaad een nederlandse versie het zelfde probleem is er in XP en Vista
Indeed a Dutch version. the same problem with XP and Vista

Something else todo:
When you don't install BOINC as a service it would be nice to remove the BOINC users that are no longer needed. A nice and clean install.

Ah, but they still are. The boinc_projects group for instance is still used to execute the BOINC executables.

Strange, but it seems the exe files start as current user, not as BOINC user.
In the tast list I see my current user name.
And why do I need to add a user in order for the exe to start at all.
I see Boincmgr and boinctray in the registry as programs to start,
(SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run) So they start as user upon login.

As we go on to the next computer.....
Installed as service on a xp machine.
I got the message (after logging in as user) that I should make this user part of the boinc_user group.
Ok I did that, logging in again, same message.
Added the user to boinc_admin.... and it works fine. But not the safest way.

Any Idea, did they test the installer...?

Another thing when I click 2x on the taskbar icon again. I get another BOINC Manager. So 2 in total. It stops at 2.....

I've experienced the same problem as I upgraded a working version of BOINC to 6.4.5 on my Vista SP1 machine, and specifically making sure to select "Allow other users on this computer to control BOINC".

Still, I can only seem to run the BOINC Manager as an Administrator, even though the privileges seem to have been set up correctly:

members listed in boinc_users group: \Everyone
members listed in boinc_projects group:
members listed in boinc_admins group: (BUILTIN\Administrators (S-1-5-32-544), Windows

I've also noted that I no longer have viewing rights on the directory "C:\Program Files\BOINC\", in Windows Explorer, though I seem to recall I could usually see the directory content, even as a regular user.

I then uninstalled BOINC (also deleting the BOINC directory) and re-installed it again, but with the same results.

I'm not sure whether this is a BOINC problem or a Vista-UAC issue. Any input or suggestion is welcome.

Anyway, here's the content of my registry, for reference:
INSTALLDIR C:\Program Files\BOINC\
SETUPTYPE Service
LAUNCHPROGRAM 1
ENABLELAUNCHATLOGON
ENABLESCREENSAVER
SERVICE_DOMAIN
SERVICE_USERNAME
SETUPSTATESTORED TRUE
MIGRATIONVERSION
MIGRATION TRUE
MIGRATIONDIR C:\Program Files\BOINC\
RETURN_REBOOTREQUESTED 0
REBOOTPROMPT
RETURN_VALIDATEINSTALL 1
DATADIR C:\ProgramData\BOINC\
ENABLEPROTECTEDAPPLICATIONEXECUTION 1
ENABLEUSEBYALLUSERS 1
ENABLEPROTECTEDAPPLICATIONEXECUTION2

I can confirm BucketSam's (preceding post) results, however I am running Windows XP x64 sp2, so it's a BOINC issue, not a Vista one.

The lack of rights to even view %ProgramFiles%\BOINC is very strange, no other %ProgramFiles% directory on my system has restricted read rights.

First up I granted everyone read rights to %ProgramFiles%\BOINC, didn't help.

Then I modified the groups from:
members listed in boinc_users group: \Everyone
members listed in boinc_projects group:
members listed in boinc_admins group: BUILTIN\Administrators (S-1-5-32-544), Administrator

to:
members listed in boinc_users group: \Everyone
members listed in boinc_projects group: \Everyone
members listed in boinc_admins group: BUILTIN\Administrators (S-1-5-32-544), Administrator, Kurt

which did the trick.

Many thanks to Kurt_Aust: his suggestion fixed the problem.
