I am trying to install the Ubuntu One Windows Beta program on Windows XP, but I keep getting the following error:

"This installation package cannot be installed by the Windows Installer service. You must install a Windows service pack that contains a newer version of the Windows Installer service."

I have XP SP3 installed, and fully updated.

Any ideas?

You probably need Windows Installer 4.5. This is covered in the Ubuntu One for Windows beta test FAQ which includes a link to download.

Thanks for that :) I wonder how I missed that when I was looking before. I'll look harder next time. – Valorin Dec 1 '10 at 6:13
