• olakara AxWebBrowser/mshtml: how to calculate physical page breaks position

• Richard Warlow Detect if IE is running

  How do I detect if IE (or any program) is running on the target machine from a Visual Studio Setup Project I want to check this as a launch condition prior to starting the setup. Thanks.

Custom actions don't help because despite names like "before install" they in fact run towards the end of the installation. well you would have to create a custom action, something like beforeInstall then check the processes running using the System.Diagnostics.Process class, getting the list of processes which are internet explorer (i ...Show All
