Change date format for wine (Windows software)

Solution 1:

1. Open Terminal, run:

   wine regedit
   

2. Follow path:

   HKEY_CURRENT_USER\Control Panel\International
   

3. Change the entry sShortDate to dd/MM/yyyy (notice the capital M)

   

Solution 2:

I was experiencing the same difficulty and this answer was of great help. The only thing is the regedit entry was reverting back to default each time I run the application. This was happening because I had to set LANG=pt_BR.utf8 before calling wine <myapp.exe>.

So the solution for me was:

1. issued export LANG=pt_BR.utf8;
2. followed user.dz's steps;
3. run wine <myapp.exe>

My application also demanded arial.ttf font, which I downloaded to ~/.wine/drive_c/windows/Fonts.
