Installing on a 64-bit Windows Server 2008 R2 Enterprise SP1 machine, the installer stops with the error:

Failed to add user to the 'boinc_admins' group (Administrator).

Any ideas what the problem is?

Thanks

Yes, you haven't read the release notes.

BOINC 6 incompatible with Domain Controllers

The present range of BOINC 6 is incompatible with Domain Controllers, meaning that you cannot install it on your system if it is a DC. This is because the developers used the Local Account API's instead of the Global Account API's.

Install BOINC 5.10.45 instead, even though this doesn't support GPUs or multi-threading applications.

Windows Server 2008 R2 Enterprise SP1 is a domain controller.

Thanks for the quick reply. I have this running on 3 other machines with the exact same OS. None of them are configured as DCs.

By 'this' you mean BOINC 6?

But the error you get is a Windows error. You could manually add yourself to the boinc_admins group. Use net localgroup boinc_admins your_user_name /add (Enter) to do so. I think that requires a reboot.
