Execution of an installer from another installer

[TrifonovS]

Hi!

I have the following problem. An year ago I made an installer that installs company specific tools. It is made with NSIS script. Now I made another installer (again with NSIS) and I need the tools from the installer that I made before. So in my new script I simply extract it to the temp folder and call with (with ExecWait). But it never runs. When the installation is finished and I try to execute it manually, all works fine, but not until my new installer runs. Probably my explanation became complicated, but I simply want to execute NSIS installer from another NSIS installer and this didn't work. Is there any explanation about it?
