64 bits application starting 32 bits process

问题

I'm working on a 64 bits application coded with .Net 4.0, C#.

In this application, at some point, I need to start another exe file using the following code :

l_process.StartInfo.FileName = _sFullFilePath;
l_process.StartInfo.Verb = "Open";
l_process.StartInfo.CreateNoWindow = true;
l_process.StartInfo.Arguments = l_sParams;

l_process.Start();

Now, this external application being compiled under 32 bits environment (x86), I get the following error :

**The specified executable is not valid for this OS platform**

Is it even possible to do so ? If yes, how can I manage to start this application from mine without having troubles ?

回答1:

Usually, no extra work is required to run a 32-bit program on 64-bit machine.

1. Try to run 32-bit program individually.
