Does this work in Windows 10 & if not is there a different way to achieve the same result?
Steve,
I just tested it on my 64-bit Windows 10 Pro, and it's working without issue.
What file type (ex: .reg) does this happen with? All, or a specific one?
As a test, see if this works below to open it with Notepad. If not, then there's some sort of association issue.
- Right click on file.
- Click on Open with.
- Select Notepad.
It's on all files. I did your test, and it opened in Notepad. However, when clicking Open with, then clicking Choose another app, I got the same error message. I then used the fix you wrote about at Open with "Choose default program" Error - Fix and it fixed it. The Open with Notepad is still throwing the error.
I must admit that I'm not sure what's causing this other than some sort of association issue.
Did you use some sort of registry cleaning program by chance?
If you know when you started to get these errors, you could do a system restore using a restore point dated before they started to hopefully sort it.
