The primary reason VMware Tools upgrades or fresh installations fail on legacy operating systems like and Windows Server 2008 R2 SP1 is a missing SHA-2 code signing support patch. Because newer VMware Tools versions (specifically 11.1.x and above) exclusively use SHA-2 digital signatures, unpatched systems fail driver signature verification, causing the setup to abort with generic driver installation errors.

By combining these resources with KBVMware and Article 78708, you can become a virtualization expert and take your IT infrastructure to the next level.
You could try installing an older version of VMware Tools (e.g., version 11.0.6 or earlier) which may still use SHA-1 signed drivers. However, using older versions is not recommended as they may lack important security fixes and features. Installing the updates is the proper, long-term solution.
