Check before uninstallation using Custom Action - Wise installation Studio 7.0

Hi friends,

I just started using Wise installation Studio 7.0. I need some assistance from you for applying conditions during uninstallation. I have to check for a process whether it is in running condition (which will be listed in Task manager) before proceeding with the uninstall procedure.

Please suggest me how to proceed with this???

Thanks in advance
