Unable to install latest Windows driver ver 7.5 M1

[Fb43]

Downloaded "DisplayLink USB Graphics Software for Windows" ver 7.5M1.During the installation, received an error message: "The feature you are trying to use is on a network resource that is unavailable (see attached)".
Before that I had ver 7.4.5. Now, the diplaylink is not working, and i am not even able to remove the previous version using the Control Panel.

Oh, and btw, the link to the latest doc, at http://displaylinkmanuals.s3.amazona...rManual7.1.pdf, returns this:

<Error><Code>NoSuchBucket</Code><Message>The specified bucket does not exist</Message><BucketName>displaylinkmanuals</BucketName><RequestId>088C9A9C51427E66</RequestId><HostId>CYZTQqDjhIEfWptZFvAjgYuP8FzWzkZw QXKyw0hs9Rxo+cdT+CIt/W5XfBGEvY0Z</HostId></Error>

Do you guys do QA? Or test your links?
