Hello experts. I am running Windows2000 and have IE6 and Netscape7 browsers.My problem is that whenever I open IE I get the Windows Installer box saying " The feature you are trying to use is on a network source that is unavailable". It appears to be looking for something called 'data1.msi' in C:\SWD\-3S8L16R.ABF\IMGWIN\MS0200EA\EN. When I click the cancel box I get the message "failed to redirect" and this situation re-occurs when browsing. However, it is only a problem on IE and does not seem to happen in Netscape. I've tried most of the obvious things but to no avail. I did dabble with Purityscan and wonder if this is the culprit ...any advice will be gratefully received.
