What exactly do you mean with the 'pearl 2010 visualizer'?
In general you find all the old software here:
https://web3.avolites.com/software/downloads/archive- there wasn't a dedicated software for the Pearl 2010. If you need the software then 'Pearl 2008 Software Version 1.1' is what you want.
- if you are looking for a simulator ('Offline Version') then 'Pearl 2004 Simulator V1' is it
- if you are brave enough to look for the ancient visualiser (which simulates the fixtures and their beams) then 'Visualiser v7.40' is the solution
