The registry key seems to set the IEXPLORE.EXE path to defaults. Are we saying that if this path is incorrect QuickClean will not launch?
I agree that it is best to let us post links to tools, reg files etc. If you find a tool or FAQ that was used in support, try to get the name of the tool or FAQ. Most of the time we host these on our download site. Once we know the name or the tool or the FAQ, we can post the official McAfee link here for all to use.
That is an interesting question. I reproduced this by removing the registry key pointing to the IEXPLORER.EXE path. This is a Microsoft regsitry key and I am not sure about our policy on fixing their registry keys. I will surely bring this up to engineering to see if there is an alternate way of launching QC instead of relying on this registry key.
I will add a registry patch on our download site. Will that be okay for you to use?
