To confirm that the problem is what I think it is, please run the following commands in an Elevated Command Prompt window and post the results.
REG QUERY HKLM\SOFTWARE\Classes\Wow6432Node\TypeLib\{EE574957-4077-4AD6-8658-327C2C86C5AA} /S

Here are some instructions to make life easier :)
1) To open an Elevated Command Prompt Window (the ECP window), click on Start, All Programs, Accessories – then right-click on Command Prompt, and select Run as Administrator. Accept the UAC prompt.
2) To run the commands easier, highlight the block of commands, and right-click on the highlight – select Copy. In the CP Window, click on the black/white icon at top left – select Paste. The commands
will run but may not complete the last command, so hit the Enter Key once.
3) To copy the results... click on the Black/White icon in the top left, and select Edit... 'Select All', and hit the Enter key - then use Ctrl+V or r-click+Paste to paste it into your response.
