I am getting this:

```
> The exit status code '1' says something went wrong:
stderr: "'C:\Program' is not recognized as an internal command
or external, an executable program or a batch file."

```

I am using wkhtmltopdf to generatepdf under laravel, and it is working fine. I use windows for local project. Now when I try to generate it, I get this error. Nothing change, laravel updated and just my .env file I accidentally deleted. 
I create a new one, but either I get a totally blank page for all my project or I get this error when I do ajax request for generating pdf.

I try in .env (by phpdotenv 3):

```
WKHTMLTOPDF='"C:\\Program Files\\wkhtmltopdf\\bin\\wkhtmltopdf"'

```

config/snappy.php:

```
<?php

return array(

    'pdf' => array(
        'enabled' => true,
        'binary'  => env('WKHTMLTOPDF'),
        'timeout' => false,
        'options' => array(),
        'env'     => array(),
    ),
    'image' => array(
        'enabled' => true,
        'binary'  => env('WKHTMLTOIMAGE'),
        'timeout' => false,
        'options' => array(),
        'env'     => array(),
    ),

    'binary' => env('WKHTMLTOPDF'),
);

```
