Studio 2017 as a default programme

Question

Since I upgraded from Studio 2015 to Studio 2017, I have got problems with some file-program associations. 
 Studio 17 is the default program to open .sdlalign, .sdlppx, .sdlproj, .sdlretrofit, .sdlrpx, .sdltm, but I cannot select it to be the default program to open .sdlfiletype, .sdltpl and, more seriously, .sdlxliff, which canot be changed from "unknown application". 
 I think I know how it should normally be done, as I had the same problem with some MultiTerm file types and I could solve it smoothly. 
 I performed repairs and even new setups of Studio 2017, losing time and settings: no way! Has anyone got an idea which might help?

Hi Gérard, 
 
You didn't mention what OS you have, but for W7 try this article: 
 
 support.microsoft.com/.../windows-7-change-default-programs 
 
For W10 try this: 
 
 support.microsoft.com/.../change-default-programs-in-windows-10 
 
You should be able to set the defaults for specific filetypes in here too.

Hello Gérard, 
 
I think that if this doesn't work and if you have had problems before... and if you have tried the repairs etc. then you should log a support ticket as this is an installation issue. This can be achieved really quickly using this link:

Just fill in the form and submit it. Make sure your email address is entered correctly or nobody will be able to get back in touch with you.
