C6W1 - Problem opening a LearningGrids resource directly through Clicker 6
- Clicker 6 for Windows
- Clicker 6 for Mac
When trying to run one of the "Free Resources" within Clicker 6, you receive an error message stating it is an "Unsupported File Type", or that the Clicker Set is "corrupted", or nothing happens at all.
When you run a free resource within Clicker 6 (from the "Free Resources" section in Clicker Explorer), the resource file is "streamed" to your computer. This means that Clicker 6 opens the file immediately and loads any remaining data from the Internet as it receives it (similar to videos on YouTube). This removes the need to wait for the entire file to download.
Firewall software or proxy servers can interfere with this process and prevent Clicker 6 from downloading free resources successfully.
Such security systems are designed to block viruses, unsuitable files and content from being downloaded, but they can sometimes block legitimate downloads.
A workaround is to access www.learninggrids.com using a web browser instead of Clicker 6. You can download the resource as a Clicker Set (.clkx) file, which you can then open in Clicker 6.
If a firewall is installed on your computer, you can resolve this problem by adding the Clicker 6 program to the firewall's list of trusted programs. It is located here:
32bit Windows - C:\Program Files\Crick Software\Clicker 6\Clicker 6.exe
64bit Windows - C:\Program Files (x86)\Crick Software\Clicker 6\Clicker 6.exe
If you are unsure how to do this, or if this does not resolve the issue, please pass the following information to your ICT Support.
Information for Network Administrators
Clicker 6 uses the default internet connection and proxy settings to connect to the Internet. When a user downloads a resource from the LearningGrids website, the following happens:
- User clicks the Run now button.
- The user's web browser requests the page http://www.learninggrids.com/ResourceStream.aspx?... (the exact URL depends on the chosen resource).
- The web server will respond by sending back the file to be downloaded. In the response, the web server sets the mime content type in the HTTP header so that an application or web browser can determine how the file should be used.
Users may have difficulties downloading resources if unknown mime-types are being blocked, either by a firewall or a proxy server. The LearningGrids website always uses standard internet protocols (HTTP on port 80) so you should be able to ensure that content is not blocked. If your firewall or proxy server is preventing files from being downloaded please try the following:
Allow the following MIME types
You may need ensure the following MIME types are allowed through the firewall via HTTP for web site access (and SMTP if you wish to allow these files to be emailed):
If your firewall supports it, we recommend adding the wildcard:
Alternatively, you can add each MIME type individually:
These files are written in XML and do not contain any executable code or registry data.
Add LearningGrids.com to your list of safe sites
If your firewall or proxy server allows you to specify safe websites, please add a rule to allow the address www.learninggrids.com, or add this address to your list of safe sites. If your firewall only supports IP addresses you can use 18.104.22.168. Only Crick Software web sites are hosted at this IP address. If you need to specify other information, the protocol is HTTP and the port number is 80.
Mark the following URL as safe
When a user downloads a file from our website, they always do so through the following URLs. To ensure these URLs are not blocked, add a rule to always allow these URLs.
