Hi all, I wanted to uninstall an instance of BOINC as I'm moving it to another machine.

OS: Windows 10, 32-bit, installed as service
V: BOINC 7.6.33, VirtualBox 5.0.18

Upon trying to un-instsall I was presented with the below errors and now cannot un-install, repair or re-install BOINC on this machine.

1st Error: Failed to obtain the SID for the selected user on LocalHost
2nd Error: Failed to delete 'boinc_admins' group

Now the installer bombs out every time I run it.

Would appreciate any ideas? Thanks...

Doing a search on the error in Google, I find that this happens when you do have the rights to install BOINC as a service, but do not have the rights to actually run it as such. The fix seems to be as simple as to reset the password on the local admin account that one picks for the install, or use a different administrator account to do the installation.

I would start with the first option, though, reset the password on the administrator account you try to uninstall BOINC with. If you weren't even using an administrator account to try to uninstall BOINC, then make sure you do so.
