Ok, I was able to get around this by going into C:\ProgramData\Package Cache and deleting the appropriate directory related to the older version. I then "uninstalled" that app from Add/Remove programs. It said there was a problem and asked if I wanted to remove it from the list. Said Yes. Then went to the second installation with the same name and was able to uninstall it. Now I am going to install with the latest version from Intel.
The Samsung laptop is nice, but their Software Update utility is bad. I'd rather update drivers/software directly from the manufacturer.
Thanks for the details on uninstall. I had 2 copies of proset at the same version in my programs (windows 8) with the error can't upgrade and a message to uninstall manually, with no other details. I Deleted one of the folders in package cache as you say, not the ones ending in 15.x.x, one of the other ones of intel's, and then I ran uninstall from Programs in the windows 8 control panel with no problems. Having removed the Intel card a few weeks ago and replaced with a Broadcom and now cleared out the proset app\drivers my Samsung 700t is working well. Assuming Intel fix the broken driver for the card I might reinstall the Intel card for widi but that I suspect will be some time away on intel's past performance on this issue... thanks again...
