I have a user who tried to installed Windows Installer 3.1 directly from the CD I shipped rather than just using the Setup file which handled it automatically, and now she's getting the following error when she tries to install the software:

Not enough storage is available to process this command.

I've seen enough info online to think it is related to Windows Installer 3.1, but I don't know how to resolve the problem.

I have successfully installed the oftware on half a dozen Vista Home Premium SP1 machines with no troubles, so I know it will work- I just have to get past what (I hope) is a simpe problem.

Can anyone help me with this please?
