The installation URL is the web address where your activeCollab setup will be installed.
For example, if you want to install your activeCollab at http://www.example.com/projects, then you should put http://www.example.com/projects into the Installation URL field on the purchase form.
In case you are unsure about the exact URL you are going to use, you can enter http://www.example.com or localhost and complete the order.
The Installation URL can then be changed later from your activeCollab.com profile:
Your URL change request will be approved automatically and soon after you will receive an email with further instructions. In case you make a mistake and wish to change your installation URL again, just repeat the same process and you will receive another email. However if you want to change your Installation URL for a third time in 24 hours, then you will have to wait for a manual approval from us. After our team approves it, you will receive an email with further instructions.
After changing the installation URL, you will need to download the license.php file again, overwriting the old one with it (it is located at /config directory). If you are not sure how to do this feel free to contact us and we'll help.
