Clicker 7

Can't open a LearningGrids resource in Clicker 7

While browsing LearningGrids in Clicker 7's Explorer, you click a resource's Run Now button but nothing happens.
You may receive an error message saying Unsupported File Type or that the Clicker Set is corrupted.


Firewalls or proxy servers can block Clicker 7 from downloading resources.

If your computer has a firewall installed, try adding this location to the firewall's exclusion list:

32-bit Windows - C:\Program Files\Crick Software\Clicker 7
64-bit Windows - C:\Program Files (x86)\Crick Software\Clicker 7

If you're unsure how to do this, or it doesn't solve the issue, please pass the following information to your IT Support.

Alternatively, access using a web browser instead of Clicker 7. You can download the resource as a file, which you can then open in Clicker 7.

Information for IT Support

Clicker 7 uses the computer's proxy settings to connect to the Internet. When a user downloads a resource from LearningGrids, the following happens:

  1. User clicks the Run Now button.
  2. Clicker 7 requests the page (the exact URL depends on the resource).
  3. The web server responds with the resource file. In the response, the web server sets the MIME content type in the HTTP header, so the computer can determine how to use the file.

Add to your list of safe sites

If your firewall / proxy allows you to specify safe websites, add a rule to allow

If it only supports IP addresses: and

If you need to specify protocols: HTTP (Port 80) and HTTPS (Port 443)

Disable "Do not save encrypted pages to disk"

This Internet Explorer setting is disabled by default. If enabled, it prevents files being downloaded over HTTPS, leaving Clicker 7 unable to download resources from LearningGrids.

The setting can be found in the Advanced tab of Internet Options in Control Panel. The corresponding Group Policy is:

User Configuration - Windows Settings - Administrative Templates - Windows Components - Internet Explorer - Internet Control Panel - Advanced Page - "Do not save encrypted pages to disk"

Allow the following MIME types

Ensure the following MIME types are allowed through the firewall / proxy via HTTPS (and SMTP if you wish to allow these files to be emailed):

If the firewall / proxy supports it, we recommend adding the wildcard:


Alternatively, add each MIME type individually:

.clkx application/vnd.crick.clicker

.clkk application/vnd.crick.clicker.keyboard

.clkp application/vnd.crick.clicker.palette

.clkt application/vnd.crick.clicker.template

.cadoc application/vnd.crick.clicker.appdocument

.clks application/vnd.crick.clicker.sentences

.clkd application/

.clkb application/vnd.crick.clicker.books

.clkc application/vnd.crick.clicker.connect

These files are written in XML and do not contain any executable code.
