I looked at the files uploaded into the case. The line that specifically caught my attention is (redacted for privacy):
May 13 09:31:10 mac02480001 installd[23305]: PackageKit: Executing script "./preflight" in /Users/xxxx/
Desktop/Symantec Endpoint Protection.mpkg/Contents/Resources
May 13 09:31:10 mac02480001 installd[23305]: PackageKit: *** launch path not accessible
(oddly, I do not see the 'VolumeCheck' message in the install log included with the Profiler.)
When I looked at my installer package, the preflight script has the permissions -rwxr-xr-x. Can you confirm this to be the case on yours? In fact, all of the scripts have the same permissions, as do the folders.
I looked through the (very long :) ) list of installed apps and couldn't really tell for sure, but it seems this machine is used for development--is that the case? Is the machine on which the install worked used for development? Just wondered if something about a development package might be affecting installations.
Thanks,
