Many thanks for this, I've tried to implement the task although my paths are different to yours..
C:\Bitnami\suitecrm-7.7.8-0\php\php.exe -c C:\Bitnami\suitecrm-7.7.8-0\php\php.ini -f C:\Bitnami\suitecrm-7.7.8-0\apps\suitecrm\htdocs\cron.php
When I run this at the command line I get the error "Bad data passed in"; and a little string of HTML?
After some more searching I've found this, but it does not as yet have a resolution....
Not to clear on PHP I'm affraid, can you see what I'm doing wrong here?
