ja, during installation ask should the assoc be done...
just like when you select for program components, similar select for file assocs and shortcuts.
then, all these settings can be on one page...

and if it can be (dunno what msi packager you've got) three state selection for the assocs would be cool.
0 - do not install
1 - do install the file assoc
2 - force install even if there are old assocs

and obviously, if someone wants to remove kixtarter, the previous assoc must come back, right?
