Prepare the Installation Environment
1 Shut down any anti-virus programs running on your system. A virus scanner could severely degrade performance.
2 Unset the environment variables. These environment variables can cause problems with web services and conflicts with Progress utilities. Enter:
unset DLC
unset PROMSGS
unset PROTERMCAP
You also should remove any references to Progress from the PATH.
3 Add the Java you installed for QAD Enterprise Edition to the PATH.
For UNIX/Linux:
export PATH=[PATH TO JAVA]:$PATH
For Windows, you must run the command from a command prompt as an administrator:
setx PATH "[PATH TO JAVA];%PATH%" /m
For the environment variable to take effect, you must close and re-open the command prompt.
Note: Windows installations require additional pre-installation steps. See Windows-only Installation Requirements for detailed instructions before proceeding.
