Unable to install MemryX runtime v2.2 on Windows

I was upgrading a previous 2.0 MemryX runtime & driver installation, which was working just fine.

Here is the steps I followed:

  • Downloaded MemryXInstaller.exe;
  • Ran it as Admin;
  • Checked in Device Manager and saw accelerator connected;
  • Next step failed:
    PS C:\Users\degirum> acclBench --hello
