I just upgraded from Windows 7 to 10 after a factory reset of Windows 7 to speed up my laptop. Since reset and upgrade File Manager closes itself within a few seconds of opening. One error log is copied below.

I have read that deleting or renaming C:\WINDOWS\system32\IDTNC64.cpl or uninstalling any IDT programs can fix this problem but despite having an HP laptop I can't find the file in system32 or IDT in Control Panel. I am also getting an atibtmon.exe run-time error but this may be unrelated. Can anyone help?

  • "atibtmon" sounds like some monitoring software relating to your graphics card. Have you tried installing the latest versions of all hardware drivers from the respective vendors? – a CVn Dec 25 '15 at 21:48

You crash is caused by the file ShellExt64.dll in version 0.9.1 which can be HP CloudDrive: C:\Program Files (x86)\Hewlett-Packard\HP CloudDrive\ShellExt64.dll (Source).

If you use this tool, update or remove it.

  • Thank you Andre. That seems to have fixed the problem. I really appreciate you taking the time to help :). At first I couldn't remove it because it said it was open but it allowed me to drag and drop to a USB drive (in case deleting it caused a problem I could replace it) then delete it.. – Tim Haslam Dec 26 '15 at 11:18
