    I recently installed Einstein @Home and BOINC Manager on my new PC running Win 7 Home Premium (so no access to Groups for userids) using the built-in User which has administrator privileges. Now I find that Einstein @Home only launches when I log on as 'User', and does not launch when I log on using my personal userid which has just Power-User rights.
    I found a reference to using from the command prompt "net localgroup boinc_admins 'userid' /add", which responded with a system error 5. From the page on the Microsoft site, that looks likely to be a permissions problem. But I have already given my personal userid Full access to the BOINC folder in C:\program files.
    Further suggestions would be welcome. (The ultimate fall back is to completely uninstall Einstein @Home and BOINC, temporarily grant my personal userid Admin rights, reinstall under my personal userid and then make myself a power user again. Hopefully, there is a more graceful way?)
    Cheerz, Chris Ry.

      I don't have win7, so my advice is based solely on what I've read elsewhere on the fora.

      I think you need to start the shell for the "net" command by right clicking and then select "administrative window" or the like.

      Further suggestions would be welcome. (The ultimate fall back is to completely uninstall Einstein @Home and BOINC...)

      You don't need to detach from Einstein (or any project) for that, neither do you need to completely remove BOINC.

      To adjust the access rights a repair install is sufficient (no uninstall at all).

      If you want allow access to all users, just select uninstall from the system software window; that leaves the data directory undisturbed. Then reinstall and select "Advanced" mode in the BOINC installer. For some screenshots see here.

      Gruß,

      [edit]Your personal userid will need Full access to the BOINC data folder too.[/edit]

        Gundolf,
        Thanks for the reply, and apologies for the delay in responding - I could not remember how to get back to this area.

        FYI: I have since found a designed way around my problem. I did a re-install of BOINC and this time saw that early on in the process I could click the Advanced buton and get access to two tick boxes. One was to run in Protected Mode, the other was to Allow all Users to run BOINC. I ticked that second box and continued the installation, and found that other users could indeed run BOINC.

        For the benefit of anyone else reading this, this world is Good but definitely not Perfect. Ticking that box for "Al users" does not affect any userids created AFTER you install BOINC. Only userids in existence at the time you install BOINC will get to run it. Hence I am doing another re-installation now to pick up a recently-added user who is using the PC quite a bit. But once you recognise that the user list is not dynamic, no big problem, just re-install.

        Thanks,

          Be aware that if you crunch with a gpu this will NOT work! Yes Boinc itself will work as you described but the gpu will not crunch when switching from user to user. This is a Windows thing and it is what it is, so if you are crunching with a gpu too, all units will error out when you switch from one user to another. In short do not plan to use a gpu for crunching on a machine with multiple users.
