Define virtual system variables for children applications

Question

I am currently working on a program that would run other application under given virtual environment. I am running another application like so:

Process app = new Process();
app.StartInfo.FileName = @"W:\path\to\app\some.exe";
app.EnableRaisingEvents = true;
app.Start();

Now I have faced an issue to change some system variables for application to be run. I have googled for this and could not found the solution. Anybody has any idea how to solve this problem, please help me?
Thanks.

Update

For example I want to set another PATH, JAVA_HOME, AppData variable for child application. Application could be: Google Chrome, Notepad++ or simple .bat script for command line.

does your exe works fine when you run it directly without changing the system variable? — amit dayama, Sep 07 '15 at 05:30
@S.Spieker for example `PATH` or `JAVA_HOME` or even `AppData` — iamawebgeek, Sep 07 '15 at 05:31
@amitdayama yes, this is a simple application or even a bat file. — iamawebgeek, Sep 07 '15 at 05:34
Then in that case you dont need to change the your system variable.. if you change your working directory while accessing the exe file then i guess it will work — amit dayama, Sep 07 '15 at 05:35

assuming you need to change path variable

string pathvariable=Environment.GetEnvironmentVariable("Path");
Environment.SetEnvironmentVariable("Path",pathvariable+";"+"*you new value of path variable*");

if your exe file works fine when you access it directly then you dont need to change the your system variable.. if you change your working directory while accessing the exe file then i guess it will work

Dont you think this would change the systems PATH variable, not the virtual variable for the child application? – iamawebgeek Sep 07 '15 at 05:36
