First the reason for this error appears to be a previous installation
file within installshield that either failed or just did not get
removed.

To fix this problem you need to go into C:/program files/common files/

then rename the folder "installshield" to "installshieldold". This will
force windows to create a new installshield folder that is clean of any
previous installation attempts. then close all programs and try to
install the program you are getting errors on again, I did this and it
installed fine. If this fails, you should go back into the common files
folder and delete the new installshield folder and rename the old
folder from "installshieldold" to "installshield", close programs and
run the problem programs install program again.
This solution seems to work for many error 5003 and 5004 codes, so if
you are having any error during installshield startup give a try, cant
hurt.
