I am also in a similar situation to kainjow's, although I'd rather describe it as Project Builder (1.1.1) failing to launch under 10.1.3. You double-click it, nothing happens. You place it in the dock, it gives a single bounce, you get no triangle, nothing else happens. Reinstalled and uninstalled, checked disk, nothing helps. (Re)Installed September 2001 DevTools with Project Builder 1.1, that one does exactly the same as 1.1.1. (I had earlier observed PB1.1 launching successfully under 10.1.1 on a different machine.)
One thing I could have done wrong is I installed AppleScript 1.8.2b1 update
prior to installing December 2001 DevTools. Ideally, this should not have been a problem, but this does not follow Apple's release chronology, so in
the real world who knows.
On one of the macfixit forums I remember somebody's Interface Builder
crashed on launch in 10.1.3. That person was advised to trash Developer
tools and install December 2001 anew, as opposed to installing
December over September. It is unclear what subsequently happened to
that person. (Sure I tried that - same result). The December 2001 DT installer, though, is apparently aware of the difference between upgrade and install, so I doubt that could be the answer. My Interface Builder launches successfully though.
For all I know, the Project Builder situation may be a genuine issue with
10.1.3. At the moment I don't see any solution other than to wait for
a next Developer Tools or OS X version and hope that helps.
Suggestions, anyone?
10.1.3 is young and I have not yet seen anybody report PB1.1.1 to work
under it. Would be reassuring if anybody who has these working together
came forward.
