You probably have some older files or registry settings that are missing or corrupted. Do you have the CD or files you used when version 126.96.36.199 was installed. You might be able to use that CD or file to either uninstall or to modify the install and then uninstall.
Unable to Uninstall Intel® Network Connections, PROSet, or Teams has information on modifying the registry that might get you to a place where you an install the new software version.
I hope this helps.
Thanks for the response, but wow! That's not for the faint of heart and this is a critical
I was wondering about the error generated when trying to uninstall from Add/Remove
programs ("Usage: DxSetup.exe /i/x..."). Is there documentation for DxSetup.exe
somewhere? It sounds like that is an uninstaller. And that application exists in a directory
called: C:\Program Files\Intel\DMIX\uninst. If I knew the options to choose, could I
use DxSetup to do the uninstall manually?
You could try using the command line uninstall to see if you can get around the errors. The User Guide has a section on command line installation options including using DxSetup.exe. The User Guide is on the software CD or you can download the User Guide. Look under Windows* Setup. I took a quick screen shot that can help you find the section you need. I hope this works for you.
