Is it possible to easily setup a launch condition that checks if another
product is installed on the system?
Firstly ,I descript the function steps installer.
- We must check lisence is installed before the installation of application.
- if lisence is setup then application directly.
- if lisence isn’t setup then lisence will install before the application automatically.
i use search for Registry key and value , launch condition to check if the machine is install the Lisence .the result is right.
but i question is that :
if installer package is checked that lisence isn’t setup then install the lisence ,but after complete the installion of lisence installer can't return to install the application???
