Running installers in debug mode:
Windows: from command prompt use this command to run the installer: "install.exe -D$V_DEBUG$=YES"
Linux/Unix: from command prompt use this command option to run the installer: "./install.sh -d"
Running with debug option, installer will store additional debug information in "InstallOutput" directory in the Spectrum folder. Inside this directory there will be module specific directories (Platform, Matching, Addressing, etc.). When you have problems with install/upgrade go to the appropriate module output directory and include all files with extension "log" along with all the log and txt files in the Spectrum root directory with the defect you are reporting.
Please remember to remove this directory before upgrading existing install.
