Too-small Virtual Memory blocking 3rd-party software installation

(I *thought* I had posted this query before, but can't find my own post!)

When trying to install software which uses flash-type movies as tutorials
(Agfa Scanner and Brother printer) in XP SP2 I keep getting told that the
programs need at least 3MB Virtual Memory. In My Computer | Properties |
Advanced | Performance Settings | Advanced | Change I am told I have 1151
Mbyte Virtual Memory.

I have experimented but there seems no way to install the software without
at least *starting* the movies.

Is there another setting I should seek?

TIA.
