License file corrupt error during install

Issue/Introduction
During a new DLP v10 install you attempt to browse to the license file (<filename>.slf) and receive an error message about the License file being corrupt.
This can also happen when trying to add a new SLF to an existing installation, either to extend the expiration or add newly purchased functionality to the Enforce Server.
In currently supported versions, the error message says:
"License file corrupt or improperly signed."
"Some of the specified settings were invalid."
Cause
This can occur for a few reasons.
Resolution
Most common cause:
When moving .slf files to the server, you need to preserve the original file exactly. Any changes, even a space in the file can cause issues.
There's a hash of the file contents in the file. If the .slf file contents change at all, it will not match the hash, which will make the license import fail.
A good way to preserve the original .slf file is to zip the license files, then move the .zip to the server and extract to a local directory. Then you should be able to start the install and browse to the .slf file.
Additional Information
There is a second issue which is happening currently, specifically in regard to license files generated in concert with a PLA. If you receive this error for a newly downloaded SLF file, please open a case with Technical Support.
