Resolve issue where the Spectrum 8.0 SP3 installer is hanging

Product Feature: Installation / Upgrade

Operating System: Windows 2008R2


Spectrum 8.0 SP3 installer on Win2008R2 server went thru pre-installation steps but hung with a message "refreshing environment" and will not progress further.


Customer had not set the data execution prevention (DEP) prior to running the installer.


UPDATED: October 20, 2017
Went into setting and set DEP to "Turn on DEP for essential Windows programs and services only". This will require a server restart to take effect. Once done, the installer completed successfully. See below link for instructions on how to find DEP settings:
