Need to delete trial version on installation of full version

[nishantbamb]

Hello,

We have two setups, one for demo version and other for full program. We want that when full version setup is executed it should check if demo version exists on that machine and uninstall the same if it exists. Can somebody please tell me how we can do this in InstallShield 2009?

Thanks in advance for your help.

Probably the best and easiest way would be for the full version to perform a Major Upgrade of the demo version.
