Hi, I've been running BOINC for quite some time, using client 5.8.11. I saw the newer version, 5.8.16, on the site today and tried to give it a spin. But the .msi keeps failing with non-descript errors, the kind that kick off the "Tell Microsoft about this problem" dialog box, followed by an "Internal Error 2755.1601" from the BOINC.msi file . I've tried uninstalling and repairing my existing install of 5.8.11 first, but both just result in a "Wizard was interrupted before BOINC could be completely installed" message.

What to do? Does anybody have advice on how to correctly get my BOINC uninstalled/upgraded? My 5.8.11 seems to be working correctly, but I fear I will never be able to upgrade to any future release at this point.

Thanks!

Simon

Try to reboot the computer first.

Then try to uninstall BOINC through add/remove programs. And reinstall 5.8.11

I have reported your problem to the developers. To be honest, I don't know an immediate fix for it. Although, you could try to use the Windows installer Cleanup Utility to see if that fixes things.

Thank you, Jord. Using the Windows Installer Cleanup Utility seems to have done the trick; I was able to install 5.8.16. Everything is back to normal again...whatever that means.

Thanks again for everybody's help.
