Whenever I go to the "Programs and Features" module in Win 7 I get the trusty old, "Explorer has stopped working and is restarting" my taskbar goes for a split second and P&F closes. I have gone to Event viewer to look for a reason and 9 out of 10 crashes acording to the faulting module is "msi.dll" Isn't msi the Microsoft installer? Anyway, how can I go about fixing this or troubleshooting it? It is to say the least annoying. My Computer is an Acer laptop Win 7 HP x64/8gb RAM /Core i5 430Mprocessor.
