Then install the .NET Framework 3.5 SP1 directly.<br/><br/>I don't think the runtime just stopped working because of nothing, there must be some changes to the system that you might not be aware of caused the problem. It seems to me the framework was correctly installed, however, something prevented the runtime working normally. Hard to say why without hands on the machine now.<br/><br/>Regards,<br/><br/>Jie<hr class="sig">This posting is provided &quot;AS IS&quot; with no warranties, and confers no rights.<br/>Please remember to mark the replies as answers if they help and unmark them if they provide no help.<br/><br/> Send us any feedback you have about the help from MSFT at <a href="mailto:fbmsdn@microsoft.com">fbmsdn@microsoft.com</a>.<br/><br/> <a href="http://cfx.codeplex.com" title=CodeFx>The CodeFx Project</a><br/> <a href="http://blog.joycode.com/vsto" title="My blog">My Blog (in Simplified Chinese)</a>Mon, 06 Jul 2009 11:14:08 Z2009-07-06T11:14:08Z
