ShellExecute fails: ERROR_FILE_NOT_FOUND

Question

I'm trying to start my application with my own launcher with administrator rights. The launcher works on my 64Bit Win7 but not at my 32Bit WinXP computer. The code I am using is this:

wstring fullAppPath = "myapp.exe";
ShellExecuteW(NULL,
             L"runas",                       //admin rights
             fullAppPath.c_str(),
             NULL,                           //startup params
             NULL,                           //default dir
             SW_SHOWNORMAL
             );

I use the MSVC 2010 32Bit compiler with the Qt IDE and the launcher-application and the main-application are in the same directory, which is not C:\Windows\System32. On my WinXP computer I get anytime I start my launcher an ERROR_FILE_NOT_FOUND error. (value 2) How can I solve this?

Answer 1

The solution was using an absolute path instead of a relative path.
