Windows 10: Unable to change default email app in Win 10.

Hi, I get error message: There is no email program associated to perform the requested action, even though I selected Google Chrome as my email app.

Unable to change default app by protocol or filetype.

Hi, I don't have Acrobat installed. With Sumatra as my default pdf reader, that hyperlink to a pdf docoument opens in.. yes.. Sumatra. Changing to Edge:




the hyperlink opens in... yes.. Edge.

If, as seems the case, Bluebeam is correctly associated with pdf files, I can't say why the hyperlink fails. Your guess about the protocol may be right- I don't know. If you could make any change to that to test that theory, as you suggest, that would help.

If you wish to view the relevant registry key, a convenient way to get there is via free Filetypesman - a rt click option.

 

Unable to change default app by protocol or filetype.

Hi, just considering what is shown in the Open With options, for example:



Here you can see Sumatra is my default reader.





Here you can see Sumatra and Chrome are added to the Open With list, + Edge, a system default.

The choice presented to you for .fdf, .pdfxml, .pdx for example, should depend on whether Bluebeam has correctly registered itself in the appropriate place as capable of handling those extensions.

So, for example, is Bluebeam shown in the Open With list for those extensions?

It is not enough that a program is installed that is potentially capable of handling a file type (e.g. via an Open dialogue) but that it be so registered. That is up to the author to specify.

Application Registration - Windows applications | Microsoft Docs





This opens in Sumatra, my default.

Unfortunately this option in the Control Panel now opens in Settings:



and does not allow you to do what it claims.

 

How to change default app for file type

'Open With > Choose another app' has three step, in the first it only offers apps registered for that file type. If you click 'More apps' it lists all registered apps regardless of suitability. Both these steps have the tick-box for 'Always use...' in my 18363.752. The third step, if needed, is 'Look for another app on this PC'. The 'Always use...' must be ticked before taking this step if you want the change to stick. However, WMP appears at the second step.

For a quick look at a JPG almost anything (including WMP) is more practical than Photos which on my system takes more than ten seconds just to open a photo. The OP is probably not aware that the Windows Photo Viewer is still available in W10, but hidden away. That's my default viewer for JPG.

And, once enabled, is available in Settings > Apps > Default apps.
