Can't remove Apple application support and Apple Mobile Device Support, and can't update iTunes
I can't update iTunes on Windows10. Every time I get this message (in Dutch) (scroll down for rest of the question):
Everything else I tried, like downloading and installing iTunes manually from the internet, or from the Windows store, also did not work.
So, I read the webpages of Apple Support:
https://support.apple.com/nl-nl/HT204275
and I followed the recommended steps.
Apple recommends to uninstall all previous Apple software. So I tried to do so.
But that causes problems too!
First, I deleted iTunes, Bonjour and iPod from the folder 'Program Files'.
That succeeded.
Then, I opened the folder 'Common Files' --> Apple
The next step should be to delete the folders
Mobile Device Support
Apple Application Support
But whatever I try, I can NOT delete them. I keep getting the message that some files are still in use.
I tried to close all files, and startup the computer again. Still could not delete them.
I went to task management, to see if some processes are using these files.
I could not detect those files.
So, I'm stuck.
Maybe I should delete something in the registry?
Please help:
1) How to remove all (previous) apple software from my computer?
so that, in the next step I can re-install iTunes again, hopefully without getting any more errors.
