Start a 64bit app from a 32bit app?

Under 64bit Windows 7, I want to start a 64bit executable(myapp64.exe) from a 32bit executable(myapp32.exe). Can I use CreateProcess, ShellExecute or ShellExecuteEx functions in myapp32.exe to do this? Will be there any problems or limitations?

I use Visual C++ 2008 to write both myapp32.exe and myapp64.exe.

Did you already try some of these APIs? What problems did you get?

I did it in the past with ::CreateProcess() and didn't encounter any problem.

You can use any of the functions you've mentioned to do this.
