Bluetooth driver 6.5.1.4500 install issue [ Edited ]

[Puppy]

I downloaded latest ThinkPad Bluetooth with Enhanced Data Rate Software for Windows 7 Version 6.5.1.4500 but I had to rollback it to the previous version 6.5.1.2700 (X220, Windows 7 x64).

 

There were several Windows warnings about attempt to install an unsigned kernel driver during the installation. How can Lenovo even publish this ? The package also contains Microsoft .NET 4.0 Framework installation that have installed unnecessary Extended (full) version of the framework during the setup while the Client Profile was already present on the machine. This leads to more security issues because Windows Update have to be performed to get security updates for the Extended (full) part of the Framework

This is already third Lenovo driver update I had to rollback in several last months. Is there any quality assurance department ? I can't remember such issues with Lenovo/IBM ThinkPad products in the past.

There's no such driver issue in this package. I've rechecked it to be sure. See below.

Likely you have a corrupted or altered download, or your your system is corrupted or infected.

Strongly recommend you scan your system and the download with multiple anti-malware products.

(Good malware products include Microsoft Security Essentials, Malwarebytes, and HitmanPro 3.)

To check the download, here's the SHA-1 hash: 06794d733f19d69a273935fac0ceeb32651b0766

(A good hash tool for Windows is winhasher.)

(Lenovo should be publishing hashes for downloads, but that's another issue.)

The executable file is digitally signed by Lenovo so any possible content corruption would result in failed digital signature validation. I see http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/g4wb12ww.txt

There is updated revision 02 of the same package released after my report that installs without the issue.
