If this app has truly disappeared, you could try reinstalling it from the original disks.
Before that, try using Spotlight to search for all instances of "Director" and see what it turns up.
On the subject of IE 5.2 for Mac. Hopefully that was just a statement of what you have on your machine, not an admission that you actually use that outdated, and not secure, browser.
IE5.2 has not been updated since 2001 and has not been supported by MS for a number of years.
Recently updated to OS 10.4; then had to download a new driver for my HP PSC 750 printer. All is well until I try to launch the HP Director. Nothing happens. In fact I can't find the HPO Director anywhere except as the alias I placed in the dock. Nothing in the HP Photo and Imaging Director folder.
I have read numerous forums discussing this problem and offering solutions, but all refer to an incompatability problem with IE7. I am of course using a Mac, and I run IE 5.2 for MAC, so none of those solutions help - at least I don't think so.
