Hello,
I have the following error when launching fresh install of Casper 8.52 on a OS X Server 10.7.4 and it doesn't launch

Matt, Do you have another user account on that machine you can try opening the Recon application under? If not try doing that and see if the profile you are using is corrupt. I had something similar happen and it was that the user profile.

Alan

Thanks Alan,
It was due to an incorrect profile. I've created another admin and was able to use Recon without issue.

I'm getting the same error and have been on a number of Macs OS 10.6, 10.7 & 10.8. This happens on any number of accounts and on a newly enabled root account on a fresh from the box.
Any other suggestions?
Thanks,

We had a very similar error like that right at the launch of recon. It had to do with the .GlobalPreferences file not having a language and a keyboard selected. You might try switching the language away from English and then back to English and see if that makes a difference. If that is the case you'll want to look at pushing a new .GlobalPrefereces file out to your affected machines.

Good luck,
Brad

Just ran into this same issue (Jamf v8.62, OS 10.8.2) and resetting the language worked.

Thanks
