yeh as i said on a fresh install it worked fine. Thanks to the site mod for his answer, but the purpose of my post was to hopefully find the 1 thing im running thats incompatable so i dont have to uninstall all that stuff. At the end of the day its a working pc and if ive installed it im useing it, im not going to remove a heap of stuff to get 1 app working. But if there was a list of apps that definatly conflict, or if someone has had similar trouble and worked out what it was it would save me a lot of hassle. Other then .net and .net2 i have no other runtimes installed. So im asumeing its an application it dont like. Im disabling my antivirus and spyware catcher but im sure theres something im missing.
