Hey,
I haven’t set it up via Windows, so I may not be the best person, but I’ll give it a shot
Have you tried running the .bat file manually?
If so, what were the results? Do you see any activity in the CRM?
Your .bat file’s code seems to point towards the CRM’s path, when looking for “php.exe”
I’d expect the last line in the .bat to be something like C:\xampp\php\php.exe -f cron.php
(Or, pointing to the location of the “php.exe” in your environment)
For your environment, is the /suitecrm/ directory where the “php.exe” can be found?
Additionally, I have found a thread regarding xampp issues
It may be worth having a read through this, to see if anything resolves your issue
Does anything above help?
