0xC004F027 licensing service reported that license is tampered - cant login or activate

[Kent_Diego]

Hi all,
I just installed Beta2 as upgrade of XP.It took a while but worked
OK. I activated sucessfully and then ran Windows Update. Upon re-boot I
cannot login to Windows. Get message: "You cannot login because you have not
activated your copy of windows.Please activate and try again. Error
Information 0xC004F027 The software licensing service reported that the
licence is tampered."
So how do I activate when I can't log in?

TIA Kent

Boot to safe mode and uninstall any disk mounting software such as Daemon
tools, Alcohol 120%, etc....
This is a known bug and will be corrected in the next build.

I fixed it! When I upgraded from XP to Vista the install program would not
let me upgrade until I uninstalled Daemon Tools.I looked for uninstalled
remains from instructions at Daemon Tools website forums. I could not find
anything in RUN>REGEDIT >
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services or
C:/Windows/System32/Drivers. I see some old left over ATI drivers in the
Services registry. I recienetly added a nVidia card to use Aero. I deleted
the ATIxxxxx.xxx entries and files and re-booted. Everthing is working now!

Be sure to report the bug and the workaround to MS. It is a good catch.

I spoke too soon. This error has come back. If I re-boot it will useally
fix.

I think it is fixed now. I think the cause was that the XP installation I
upgraded from had Kaspersky antivirus. It did not seem to be present after
upgrade but the Windows security advisor thought I had antivirus running. I
uninstalled Kaspersky and have not had anymore trouble.
