Uninstallation of installed pre-requisites

Hi,

I have created an installer which checks if the necessary pre-requisites are installed
and if not, will install the same using ExecWait. During uninstallation, I want to uninstall
these pre-requisites if they were installed by us in the first place but leave them if the user already had these softwares installed. How can I achieve this?

Thanks in advance for your help.
Regards,
Srividya

You'll need to store some variable(s) somewhere that tells you that you were the one who installed requisite 1, 2, etc.
- In registry
- In an ini file
- as an appended byte to the unintaller exe.
