Hi We have a machine here at home with Windows Vista installed. However quite recently every time any executable file is launched, such as to install an application, a message appears saying "Internet Explorer has encountered a problem and needs to close. We will let you know if there is a solution to the problem" which of course it does not. I have looked on Google for a remedy and it appears that some people do have a similar problem but whatever suggestions are given do not appear to resolve this. I can easily rebuild the machine which will take a couple of hours. But if I install SP1 am I likely to get the same problems with Vista Pro SP1? Has anyone experienced this please? Is there a way of repairing IE7 with Vista to see if that solves the issue? Thanks. Brian Hartgen
