Answer 1

The obvious next step is to examine the value of GetLastError().

Answer 3

cant debug there, just see that run process returns false;
while exe path is correct. it works under win32, under win64 create process fails.

Answer 4

run under win7x64bit; process which calls CreateProcess is compiled for 64 bit windows.

under win32 its fine.

Answer 5

ok i get it - the last error;
Cretate process retun false with this:

ERROR_ELEVATION_REQUIRED 740

The requested operation requires elevation.

what does it mean ?

Answer 6

Hi,

I have told you, try to use ShellExecute or ShellExecuteEx.

Answer 7

It means the process you are starting requires administrator privileges. 

Answer 8

yes, it works now, i just restart to aply the admin right.
also if run create porocess and it return false with lasterror 740, then try to start with ShellExecute, which produces elevation dialog, and its done.
other way is to grant user with admin right, if possible.

Answer 9

Just call ShellExecute.  Simpler.
