I have been using WinEdt 7 and then bought a licence for WinEdt 9. Since my computer (with W7) was still treating WinEdt 7 as the default program for TEX files, I tried to change that to WinEdt 9 using the "Default programs" facility. Since that did not work (WinEdt 7 remained stubbornly in place as the default program for TEX files) I uninstalled WinEdt 7. Now, the TEX extension has disappeared completely from the "Default programs" facility.
Help please! How can I get WinEdt 9 to be recognised as the default program for TEX files?
