When I attempt to upload a keyword library from Silk Test Classic, I receive the error “Failed to Upload Keyword Library: Failed to Prepare Library for Upload”

This issue can occur when the Silk Test Project contains a file that does not exist within the project directory.  Silk Test Classic assumes that the project is self-contained and all referenced files are included within the Silk Test Classic project location.

To resolve such an issue locate the file that exists outside the project directory and paste it inside the project directory prior to re-attempting to upload the keyword library.
