Assembly Component {303994BA-6487-47AE-AF1D-7AF6088EEBDB}

I recently tried to install the Nokia Software Updater, but it gave me this error:

Error 1935. An error occured during the installation of assembly component{303994BA-6487-47AE-AF1D-7AF6088EEBDB}.

Quick research showed that this had something to do with MSXML 4.0. So I quickly went here and downloaded the msi installer. Which gave me the same error.

Apparently you have to force an uninstall of MSXML 4.0 SP0 or SP1, open a cmd-window and enter the following two lines:

msiexec /qn /x {35343FF7-939B-401A-87B3-FF90A5123D88} msiexec /qn /x {2AEBE10C-D819-4EBF-BC60-03BF2327D340}

Close and restart. Yes: you must restart (I hate it as much as you do).

Now install the msi. Then install the Nokia software. Everything works fine now.
