[Mono-list] mono c# portability

[pjaol]

Hi

I'm having problems running mono c# applications on any machine other 
than the one it's compiled upon.
I've compiled with on a win 2000 pc, and it fails on similar 2000 
(ghosted from the same image)
and also on XP machines.
The xp machine pops up the following Application Error "failed to 
initialize properly (0xc0000135). Click on OK to terminate the application"

Is there a a run time environment that has to be installed on all 
clients that run any mono c# applications?

Thanks
Patrick
