There is a possibility that due to network configuration and/or location that the ADIsimPE Update will be unable to connect.
This morning we were able to update the installer with a current license. If you have been unable to update ADIsimPE in place, please uninstall it, download the updated version from our web site (http://www.analog.com/en/design-center/interactive-design-tools/adisimpe.html), and install. After install please check the version number; it should read 7.20n. Once that version is installed you should have no further problems.
If you continue to encounter errors please contact us at firstname.lastname@example.org and we will assist in finding solution.
