URLDownloadToCacheFile error when installing Skyline and Skyline-Daily aaron-maurais  2025-12-03 10:26
 

Hello,

I am trying to install Skyline-Daily on a Windows 10 AWS instance and I am getting an error. I've attached a screenshot of the dialog that comes up with the error. I've also attached the insall.log file that is written to the Downloads folder.

The relevant lines at the end of the log file seem to be:

URLDownloadToCacheFile failed with HRESULT '-2146697208'
Error: An error occurred trying to download 'https://skyline.gs.washington.edu/software/Skyline-daily13-64/Skyline-daily.application'.

I have also tried this with the stable version of Skyline and I get the same error.

I was able to install the Unplugged version of Skyline-Daily in the mean time, but I thought it was still worth reporting this. Is there some sort of network setting that could be causing problems?

Yes, '-2146697208' is a networking error whose name is "INET_E_DOWNLOAD_FAILURE".

Here is a support request where I suggested a few ways of dealing with this error, but the only suggestion that actually worked was to use the unplugged installer:
