Bitlocker installation fails through Windows Update: 80070643
I have been attempting to install Bitlocker on my Windows Vista Ultimate
installation for several months without success.
Every time I attempt to install the program through Windows Update it comes
back with the fail error 80070643.
Investigation of this error seems to relate to problems with Office 2003,
however, I have never had Office 2003 installed on my machine and all the
suggested solutions either do not resolve the problem, or are not relevant to
This seems to be quite a common problem but I have been unable to find a
solution that works. Any assistance would be greatly appreciated.
