yeah, Dell support's become a joke; most of the old links are broken or redirect you to a generic non-sense page. If there used to be a good link in this post it would have said either uninstall / reinstall .netframework & uninstall reinstall CmndCntr which you can try 1st (basic approach, launch your 60-70Mb CmndCntr.exe app, clik repair, reboot, see if it helped, if not, uninstall/reinstall).

.net uninstalls through your control panel & is available for download either through win update or Micro$oft.com for normal reinstall:

• .NET Framework 3.5 Service Pack 1
• http://www.microsoft.com/en-us/download/details.aspx?id=22
• .NET Framework 4 (Web Installer)
• http://www.microsoft.com/en-us/download/details.aspx?id=17851
• .NET Framework 4.5.2 (Web Installer)
• http://www.microsoft.com/en-us/download/details.aspx?id=42643

CmndCntr versions are found on Dell.com: http://www.dell.com/support/home/us/en/04/Products/

(good luck, here's what I had for help tonight)
