Due to it's ability to be installed on a number of operating systems and operating system versions, the Deducer installation might need a bit of help. Below are common error messages and what can be done to resolve them. If you cannot find an error message you are receiving or would like more help, please contact: mobilize-support@cs.ucla.edu

  • Windows XP: "You must be logged in as an administrator when installing this program"; Windows Vista/7: "To continue, type an administrator password, and then click Yes"; Mac OSX: "The Item JGR can't be moved because "Applications" can't be modified"
These three messages are all displayed when you do not have sufficient administrator privileges to run the installer. Please contact your device administrator for help.

  • "Setup was unable to create the directory "C:\Program Files\JGR". Error 5: Access is denied."
This issue may be seen if you have recently updated to the latest version of Java. Please reboot your system and try again.
