I suppose I am still working on getting rid of the ASUS suite. As per the explanation, the ASUS Suite encountered a failed uninstall prior to the renaming of the ASIO and ASUpIO. Since it did not seem to matter, you have returned the file names to normal?
I will still assume the primary Suite setup utility will not run correctly? I have attached a picture of the uninstall utility, which you used to attempt the uninstall or removal. Does it look the same as yours?
I have pretty much decided the asacpi file is causing the problem. Since we cannot seem to get rid of it, we aren't getting very far. If you could find the service and stop it for testing, that would be great. Maybe in the Device Manager, like the other two, or in the Services panel. A complete uninstall would, of course, take care of the problem, if we could get that to work.
Maybe running some of the utilities that are still installed would give you a message about what was wrong, and if you could solve those, you could get the uninstall to work.
If all else fails, the ASIO and ASUpIO services are started from the registry in the following key. You may find one there for ASACPI also. If not, you have the option of downloading and running Autoruns from SysInternals, where you could uncheck the start up entry for testing.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\AsUpIO
I don't really have anything else to add, so I will stand by in case you need some info about the ASUS Suite install. Good Luck..
