Canon techhies had me uninstall, regedit, re-install from CD, download the Canon update, etc.
(Somewhere I read that the CameraLauncher.exe is not compatible with Vista anyhow but everything was fine with downloading pix from the Canon Powershot S5is before).
(I can find and download the pix by going thru the Windows Media program but the wife wants her functionality back.) (No evil snickers please).
Anyhow, HP support says to download the cameralauncher file from alternative sites.
Might be good to try, but the site they recommend doesn't seem to have it.
This is a really mundane question to ask but there must be a solution.But I think that it is a cut above the Canon/HP expertise.
