Hi Spinky106: I have similar problem with you and luckily I found your post. Your solution is really helpful to me. But I have additional problem about this topic. First, let me tell you my problem. Please reference this article. http://community.installshield.com/showthread.php?t=183774 I have some kind of idea handling this problem. The following is my steps: 1. Created a setup.exe (Basic MSI project type). 2. Follow your solutions and insert my new custom action after InstallWelcome action. http://community.installshield.com/showthread.php?t=174108&page=2 So far, everything is ok. But, I have some special requirements. 1. I hope setup.exe does not show any windows (including Preparing to Install and Welcome windows) and directly enter setup_x86.exe or setup_x64.exe. That is, the task of main installation thread (setup.exe) is: Judge the end user's platform and invoke the suitable child thread (one of setup_x86.exe and setup_x64.exe). 2. When finishing installing setup_x86.exe or setup_x64.exe, the child thread exits and the main thread continues executing. But there is no need for me to let main thread continues executing. Because the whole installation is finished. But my current situation is the setup.exe would run other its original custom actions. So, how could I solve these problems? Just give me a clue and that will be helpful to me. Thanks ... View more
