I'm trying to install Windows 8.1 (basic upgrade from Windows 8). It is complaining of Sentinel Runtime Drivers incompatibility. I've looked for it in my Programs & Features list, but it's not there by that name nor SafeNet (as related by google search) nor do I see any obvious candidates for it having been bundled with another listed application. I tried the "Sentinel Runtime Driver Cleanup" program from the SafeNet website. It ran but was ineffective, even after a reboot.

Do you recognize this "Sentinel Runtime Drivers"?

I ran MalwareBytes too, just in case, but it found nothing.

The answer was that Lightworks didn't uninstall correctly (left shortcuts and this crappy license verification service running - what trash!)

This link finished it off:

Which says get this:

And run it like this:

haspdinst.exe -purge

(I stopped the service first)

Here's the generic download link (rather than a specific version): Search for command line run-time installer. Also, use the -remove switch instead of -purge; it uninstalls everything, rather than just removing the service – Zenexer Sep 12 '13 at 4:45

Steps involved:

  1. Open the link:
  2. Click on: Sentinel HASP/LDK - Command Line Run-time Installer
  3. It will download a compressed folder named: Sentinel_LDK_Run-time_cmd_line
  4. Unzip this folder and copy its address
  5. Open the command prompt by typing cmd from the run window or from the search (if using Win 7 or 8)
  6. In the command prompt window, type cd, (space), and paste the copied address and press enter.
  7. After that, while still in the command prompt, type haspdinst -remove and press enter.

    It will take some seconds to uninstall and once done, it will prompt you.
