Hello Caylan,

Sometimes the reason for this issue is that the logged in user does not have permission as an admin. Could you answer the following questions:

• What is the version of xCode
• Are you logged in as Admin or have admin rights when running the install
• Are you running the install through command line? If so what is the command that you are using

 To troubleshoot this, please send an installation log file?

1. Open up the “Console” from Launchpad, Select “system.log” from the panel on the left, click “Clear Display” button on the top
2. Run the install and when its done copy and paste the log information into a text file and send it over

Let me know if you have any additional questions.

I've verified/repaired permissions - still shows error

I ran "chmod -R go+w /Developer" - still shows error

I'm available for Skype screenshare with you if you would like to see this first hand.

The package looks good as far as pkgutil is concerned:

$ pkgutil --check-signature Infragistics_NucliOS_2013_2_Trial.pkg
Package "Infragistics_NucliOS_2013_2_Trial.pkg":

Can you try 

chmod -R 777 /Developer

No change.  So strange... I have a project I'd like to start working on, so please consider this a high priority.  I'm available via Skype to troubleshoot this.

Hello Caylan,

I have been contacted by Ammar informing me that you were successfully able to install the trial. At this time if you have any further questions or concerns do not hesitate to ask. Thanks again.

Ammar sent me a zip file with a shell script.  I was able to manually install the trial.  The pkg still does not work on my system.  Feel free to contact me if you come up with a solution.
