You shouldn't need to set any environment variables just to run an exe. All you need to do is run the exe using its absolute path or a path relative to the directory you are in when you execute the perl script. For example, assuming this is Windows (since you're talking about an exe) if you have a directory structure like:

C:
- dira
| - a.exe
- dirb
  - dirc
    - a.pl

and at your command prompt you are running:

C:\dirb>perl dirc\a.pl

then in your perl file, you should use either

`C:\\dira\\a.exe`;

or

`..\\dira\\a.exe`;

If your command prompt is:

C:\dirb\dirc>perl a.pl

then you can use

`C:\\dira\\a.exe`;

or

`..\\..\\dira\\a.exe`;

Update

file test.pl:

$ENV{'PATH'}.= ':some/dir';
system('./testpath.pl');

file testpath.pl:

open(FILE, '>>output.txt');
print FILE $ENV{'PATH'};
close(FILE);

If you know where the exe file is, just use the path to it the same as if you were running it from the command line. In Perl:

system('c:\full\path\to\exe\program.exe');

or if you prefer to use forward slashes (they're all the same to the Windows kernel):

system('c:/full/path/to/exe/program.exe');

Try using the full path to your exe. e.g.

system("/full/path/to/app.exe");

Did you set your path like this:

To get your PATH:

$path = $ENV{'PATH'};

To set it:

$ENV{'PATH'} = 'some/dir:another/dir';
