What steps will reproduce the problem?
1. install on Windows
2. configure __PHP_CLI_PATH__ to 'C:\wamp\www\bin\php\php5.2.6\php.exe' or
wherever your php executable is
3. in the project management page, import from the data/import/# directory

What is the expected output? What do you see instead?
When the page refreshes, the operation log shows:
  There are messages from the background process: Could not open input
file: includes/narro/importer/importer.php
I went into narro_project_manage.php and modified line 399:
   $strCommand = sprintf(
   __PHP_CLI_PATH__ . ' ' .
   escapeshellarg('/includes/narro/importer/importer.php').
to:
   $strCommand = sprintf(
   __PHP_CLI_PATH__ . ' ' .
   escapeshellarg(__DOCROOT__ .
__SUBDIRECTORY__.'/includes/narro/importer/importer.php').
and import now seems to work, but operation log shows:
   There are messages from the background process: 'ps' is not recognized
as an internal or external command, operable program or batch file.
