Installation on Windows failing

[KnightCoder]

I am getting the following error when trying to install.

php install.php

 + config.php found, testing database connection
PHP Notice:  Undefined index: folder in D:\Program Files\LiteFilesystem\src\include\modules\files.php on line 26
 + Database connection established
PHP Fatal error:  Uncaught Error: Call to undefined function posix_getgrgid() in D:\Program Files\LiteFilesystem\src\include\modules\system.php:220

Please help me fix this.

这个问题解决了吗

I simply commented this line and so far it doesn't seem to have any issue on windows.

Wrapped that block with
if (strtoupper(substr(PHP_OS, 0, 3)) != 'WIN'){
and same for the file install.php Ln: 154

Additionally I added
if (isset($_REQUEST["folder"]))
on include\modules\files.php line 26 to solve the last error while calling install.php

EDIT: not getting error, was not clear to me what todo next .. I looked again and launched with force, so I had to fix another issue (#12) and than I could login successfully
