Found this in the General dicussion area:

In my case I opened a command prompt and changed to the \windows\system32
directory. Then I entered 'regsvr32 vbscript.dll' (without the quotes).

The command prompt shoud be opened with "Run as adminstrator". In my
case, the command prompt opened in C:\Windows\System32 which is where the
file vbscript.dll resides. Hence the command

regsver32 vbscript.dll

could be executed immediately.

After that iTunes+Quicktime installed with no hassle and then
Expression Media
also ran properly.
