Hello,
I'm not sure why you encountered this behavior.
Please note that based on the install conditions defined in the
install conditions tab of the prerequisite, the related prerequisite will be installed or not.
So, can you please make sure that the related prerequisite should get installed? In order to test a condition you can use the
[Test] button.
Also, be aware by the two options below the “Install Conditions” pane:
Install only if at least one condition is false -
If this option is selected, at least one search must fail in order to install the prerequisite.
Install only if all conditions are false -
If this option is selected, all searches must fail in order to install the prerequisite.
So, the prerequisite software will be installed according to the enabled option which refers to the install condition that you have defined before.
If this is not your case, can you please test on another machine and see if the behavior still persist?
Also, be aware that on Windows Vista and above, in order to silently install the prerequisites packages the main installation package should run elevated. So, from
Install Parameters page you should check
Run as administrator option.
Please let us know if that helped.
Best regards,
Dan
