Failed to download

When I try to setup 4.26 source code, it downloaded the dependencies, and gives the following error:

Failed to download ‘http://cdn.unrealengine.com/dependencies/3362661-c42b75bbdfa5405597d5cca909cf2e91/1a42a9452176f527cfbaa6dd896ca0728d81bb37’: The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters. (PathTooLongException)

What am I doing wrong?

If the path is too long, you could try to setup the source code closer to the root, like directly on your C/D/E/F whatever drive or in a folder on your drive.

Ah, that was a novice mistake of me. That did it, thanks!
