I am using 2010 Express and I need to create a conditional installation with very special condition. I can write an executable that checks the condition and add it as a custom action, but I don't know how make the installation to react on it. Are there specific return codes from executable that would force installation to abort? On which step do you recommend adding it as custom action?
