I do my Windows installs in an account with full installation rights, then use another account for general PC usage.

When I try to start BOINC under the non installation account (even though I specified other users could run BOINC), it won't load projects and keeps giving me the message "Client has exited 3 times in last X minutes. Would you like to restart it again." Needless to say, restarting doesn't help.

What should be done to fix this?

PS this is BOINC manager ver 7.0.64(x86) on Windows 7 Pro, SP 1, 32 bit. AMD Athlon 64X2 processor, Asus2 motherboard. No proxy server.

Always easy to steal from my own posts on the same subject.
I posted at Seti in answer to someone with a similar problem...

This sounds like you installed BOINC as a service, or as a protected application execution. Is that correct? See this FAQ if you want to remember what the installer screens looked like.

Do you also know where you installed BOINC to? Is it the directory C:\Program Files\BOINC\, or is it somewhere else?

What if you were to uninstall BOINC --through Start->Control Panel->Uninstall a program-- and then reinstall it, but this time not as a service? Does that work better?

Have you also made sure that the user account that you use is part of the boinc_users? To check do:

Start->All Programs->Accessories->right click Command Prompt->Run as administrator->Acknowledge.
In the command prompt window, type:
net localgroup boinc_users and hit Enter.

If your user account isn't in here, you can add it by doing net localgroup boinc_users 'username' /add, where 'username' is the username you want to add. Do not use the quote marks.

After that the computer needs to be restarted.

It wasn't installed as a service, it was in the C:\Program Files\BOINC\ directory, and it executed fine under the installation account.

However, something you said gave me an idea, so I uninstalled then installed it under my execution account as administrator. That worked. Since I basically only use the execution account with no one else really using this system, this solution works out well.

Thanks for your help, Jord.

Primarily writing @ Jord...

We seem to get enough stories like this that I really fear there's some unidentified weakness in the 'permissions and groups' setup phase of the BOINC installer, when the 'allow all users to control' option is selected.

It would be ideal if Rom, or somebody, could get hold of an absolutely pristine computer with a completely fresh Windows installation that could be wiped clean between attempts, and walk it through.

There's a temptation to use a VM for this kind of work, but it probably should be repeated with a typical mall-bought home OEM machine - preferably one with a 'restore to factory state' recovery partition. I say that because of warnings like this from Microsoft http://support.microsoft.com/kb/307545 (this is the XP/FAT32 version, but I think similar warnings apply for other versions, and other file-systems, too)

Warning Do not use the procedure that is described in this article if your computer has an OEM-installed operating system. The system hive on OEM installations creates passwords and user accounts that did not exist previously. If you use the procedure that is described in this article, you may not be able to log back into the recovery console to restore the original registry hives.

I do have to ask, the non-administrator account you ran with, was it added before BOINC was installed, or after BOINC was installed?

I now have a 'clean', factory-fresh, Windows 7 Pro machine, and have reproduced this problem. Just waiting for my report to re-appear from the boinc_alpha mail server.

Rom Walton has just posted:

Whatever the 'all users' issue is, it'll have to wait until the next 7.2
update. It looks like the 'all users' issue was around in 7.0.x as
well, so 7.2.23 won't be any worse than what it already have as a public
release.

Sorry folks, we tried. See [trac]#1025[/trac]

And I got a nice new machine to play with :-)

Still an issue w/ BOINC 7.0.64 (x64), under Windows 8.1 .

Same here. Works fine on my desktop, but when switching to another user account get same message. Also, when switching processing stops. This is on a two day old Dell xps 8700 se running Windows 8.1

Same here.

Same here, what? Excuse me for asking, but what is it you see, or don't see?

I see at Dell that your system comes with an NVIDIA Geforce GTX 660 1.5G GDDR5 videocard. I take it that this one is being used to do calculations with, and that it is this processing that stops? Well, that's then normal, as by using fast user switching, you instruct Windows to use its own built-in video drivers, that lack CUDA and OpenCL support, which is why BOINC will stop using the GPU until you switch back to the user that has the video drivers loaded that BOINC can use.

If that isn't what you see, then you will have to explain what you see.
Also tell us what BOINC version you use. See this thread for what we may need more.
