How to solve vSphere Windows Client 5.1 SSL Error

In this article, I am using Windows 7 64-bit with vSphere Client 5.1.0

This issue has been bugging me for quite some time. Whenever I search for any VM inside vSphere Windows Client, I keep receiving this message, and I have to go manually to the VM I need, which is a serious pain when you have hundreds or thousands of VMs:


I could solve it (FINALLY)!!

All I did was the following:

  1. Open Regedit
  2. Navigate to
  3. Add a new DWORD (32-bit) with name ClientMinKeyBitLength and value 00000200
  4. That’s it, Enjoy!!

**If it doesn’t exist, just right click KeyExchangeAlgorithms and click New->DWORD (32-bit) Value
