I’ve been running the Windows 7 beta for around a week now and decided over the weekend that I like it enough to use in place of Vista.
When I tried to set it up with my HP MediaSmart Server though the HP installer would constantly generate a Windows error, before displaying an error message with “RegOpenKeyExW” and then exiting.
Trying the vanilla installer from a system-builder install of Windows Home Server lead to more helpful information, and a series of steps that will resolve this problem;
For anyone encountering the “RegOpenKeyExW” with the HP MediaSmart Server/Windows Home Server, and Windows 7 try the following steps;
- Click Start button and type “Command”. When “Command Prompt” appears in the list, right-click on it and choose “Run as Administrator”
- Enter the following: reg delete HKLM\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions /va /f
- Press enter. If you receive an error you are probably not running as an administrator.
- Close the command prompt. The Windows Home Server connector software should now install successfully.
Currently you’re Windows 7 machine will be listed as “Windows Vista”, but that’s a known issue!
