X30/X50: "The software version is not found"

[jbass@srcinc]

I'm testing out an internal update server for our Studio X devices and the devices themselves are updating with no issue but the TC8s are not, in the web configurator the TC8display the error of "The software version is not found." with the internal update server but it doesn't happen with Poly's server.

This occurs with:

3.1.3-220008

3.2.1-224090

3.2.2-226104

Each update is extracted to the root of the web server. 
I have attached screenshots for reference.

Thanks,
James

This might be the solution, will look into further.

Added the following to web.config and that took care of it.

<mimeMap fileExtension=".*" mimeType="application/octet-stream" />
