c++ - Trying to get default web browser path fails on Windows 10 -


i'm doing following in app's installer (note installer project windows executable (setup.exe) , not msi.)

first needed check if there're file associations .htm , .html file types. did already. , if there's no association needed add them opened web browser.

to make lesser of impact on user's system, thought go user's default web browser. question how find path?

so doing this:

//get default web browser path wchar wbuffpath[max_path] = {0}; dword dwszbuffpath = max_path; ::assocquerystringw(0, assocstr_executable, l"http", l"open", wbuffpath, &dwszbuffpath);

which seems work, except when run on windows 10 path (when default edge browser):

c:\windows\system32\launchwinapp.exe

so how reset of parameters start it?

try using assocstr_command instead of assocstr_executable. using assocstr_executable, asking just executable itself, getting back. assocstr_command should give whole command line executable.
