There are two applications that install from network shares that have silent installations. Both application installers use installshield so the installation command follows the general form:
setup.exe -s -f1″D:\networkshare\answerfile.iss”
The .iss file is created by running setup.exe -r.
The problem here is that the silent installation works for both applications when run as a user however when run as the local admin account both installers return an error code of -3 which indicates missing information from the iss file.
