Registry search and custom actions

I need to install Flash player with my application MSI. So I did these steps:

1. Go to Launch conditions editor.
2. Right click Search target machine.
3. Add registry search
4. In the property window of the registry search I wrote:
   • Property - FLASHPLAYERREGISTRYVALUE
   • RegKey - SOFTWARE\Macromedia\FlashPlaye开发者_如何学Cr\CurrentVersion
   • Root - vsdrrHKLM
   • Value - 10,3,181,34
5. Right click Lauch conditions
6. Add Launch condition
7. In the property window of the condition I set:
   • Contidion - FLASHPLAYERREGISTRYVALUE (the search registry property name)
   • InstallUrl - Flash player installation url
   • Message - ...

The installer returns false all the time. I mean it says no flash player installed although the key allready exists in the registry and it tries to install Flash player .

I think you should rather use:

• Property - FLASHPLAYERREGISTRYVALUE
• RegKey - SOFTWARE\Macromedia\FlashPlayer
• Root - HKLM
• Value - CurrentVersion

then the FLASHPLAYERREGISTRYVALUE should resolve to "10,3,181,34" which is the contents of "CurrentVersion" registry value in your case.

To install other software with your package you can use prerequisites. Here is a discussion which may help you: Adding Custom prerequsites to visual studio setup project

A better detection criteria is checking the version for this file:
