I have a VS2008 clickonce application with a custom prerequiste, which I install with the bootstrapper.

  • When deployed online, the prerequisite is downloaded and installed fine. No problems.
  • When deployed via CD to a Windows XP machine, also fine as above. No problems.

However, when deployed via CD to a Windows 7 machine:

  • the prerequisite is downloaded - good
  • then the user is asked for permission to the run the file - good
  • then the installation of the prerequiste is just SKIPPED - bad
  • and the ClickOnce application installation begins without the prerequisite - bad

Has anyone encountered this weird behaviour? I cannot find a solution anywhere.
