Hello, I am creating simple 64 bit application. It calls ShellExecute(NULL, "open", "index.html", NULL, NULL, SW_SHOWNORMAL). I run it in Windows XP SP2 (or Windows 7) 64bit system. The issue is that it opens 32 bit version of Internet Explorer (IE). The Process Explorer tells: Current Directory - "C:\Program Files\" Command Line - ""C:\Program Files (x86)\Internet Explorer\iexplore.exe" -nohome" If I run 64 bit version of IE before I start my application, the page is opened in this 64 bit version of IE. Could you help me to open 64 bit version of IE from Windows XP (or Windows7) 64 but? Thanks, Valery.

Hello? No one knows the answer? Thanks, Valery.

Leo, Thanks for the reply. The issue is reproduced on Windows 7 64 bit. I changed my original question by adding Windows 7. Thanks, Valery.

Hi, The path of Windows 7 IE 64bit is C:\Program Files\Internet Explorer, IE 32bit path is C:\Program Files (x86)\Internet Explorer\iexplore.exe. Usually, Windows 7 x64 will run the 32-bit version of Internet Explorer by default. And there are actually two shortcuts for Internet Explorer in the "All Programs" menu. You can also try to set use IE 64 as the default internet explorer: a. Click on Start and go to Default Programs. b. Click on Associate a file type or protocol always open in a specific program. c. Browse to all the extensions where internet explorer is set as default and then click onchange. d. Now Click on browse and then go to location C:\Program Files\Internet Explorer\iexplore.exeand select it. e. Click Ok and then Close. f. Click Save. Hope that helps.
