ClickOnce fails under 3.5 SP1 RRS feed

  • Question

  • Hi,

    I have 3.5 SP1(KB951847) installed on a Vista Ultimate machine.

    When I try to install my apps using ClickOnce I get asked whether to install the framework. The 3.5 Maintenance mode dialog then comes up. When it completes  repairing (successfully) the same dialog re-appears. If I cancel I cannot install the app.

    I have raised this issue on the setup and Deployment forum:

    but it would appear that this is a framework issue.

    Does 3.5 set a launch condition in ClickOnce or somewhere in the registry that is preventing my app. from installing ?

     The problem does not occur installing on another XP SP3 machine I am testing on.

    Any insight much appreciated.

  • Problem solved - I had changed the default file association of the application manifest.

    Changed it back to Setup and Deployment Library and all is well !

    Hope this helps others.
