Hi, i am newbie.
I need some help.
when i install an application "AAA" it should look for an application "BBB". if application "BBB" exists in the system. it should abort installation of "AAA" silently

thanks in advance
Mark

There are many ways you can achieve this... you can set action on pre install

1. Read if an any existing Registry Entry are there for BBB
2. Read if any services running for BBB
3. Read if any files are available for BBB.

if any of these are existing or any application specific info for BBB is availble, Abort the installation.

Hi, thanks for the repy,
in "system search" i created Property "FINDABC" and searched for a registry of app BBB.
What should be the condition to terminate the application?
thanks,
Mark

You should check value of "FINDABC" is not an empty string, if it is not a empty string exit the installation using Exit Installation action. Hope this will help.

Cheers,
Praveen :)
