Install Windows 8.1 Preview - 0xC1900101 - 0x4000D

Trying to update on-line or with a downloaded CD of Windows 8.1 preview gave me the following problem - Bluescreen on startup follwed by system reverting to Windows 8.

This blog post pointed me in the right direction:

This site pointed me to an uninstall option for AKSDF.SYS:
http://www.pulsonix.com/faq.aspx?KB090025

 I'm not sure when this was installed (this was originally an update from Windows 7) but the following applications were installed on the same day:

• Microsoft Expression 4 video encoder

• DVD Flick (Open source DVD Authoring)

• Pinnacle video drivers (to support Pinnacle studio on the iPad)

Removing these applications didn't remove the Sentinal SafeNET driver, but thanks to the Pulsonix site, I was able to find a command line uninstaller.

1. Visit the SafeNet Downloads site
2. Download the Sentinel HASP/LDK - Command Line Run-time Installer
3. Extract it
4. Open a CMD prompt as an administrator
5. From the extracted files directory, run haspdinst -info and you should see the installed version you have, and the installer version enabled
6. Run haspdintst -r to remove
7. Run haspdinst -info again to confirm removal

I didn't try the upgrade by upgrading the SafeNet driver, just removing it.

I'm not really sure what the SafeNet software does, it's all rather vague on the site - Anyone know?

Now, just the Intel Express 4 Video driver issue to crack.
