Downloading calibration data fails

[Ryotsuke]

It looks like it is trying to download and execute an exe file

First of all that should never happen, this is unacceptable policy to download and execute code under admin priviligies. You'll get banned by every antivirus possible.

The error

[Window Title]
E:\Projects\ractiv\build\userdata\0101001920\rectifier_plus.exe
[Content]
E:\Projects\ractiv\build\userdata\0101001920\rectifier_plus.exe is not a valid Win32 application.
