Seems to me the installation routine thinks TOAWIV is still there and tries to uninstall it what fails for whatever reasons.
First go to the uninstall programs screen(sorry not sure how that screen is called in English) and see if it still lists the game, if so click it to start the uninstall and see if it works.
If you get the same error check the path in the error window if the uninstall.exe is there at all, if so start it manually and see if the same error comes up again.

Install the update with Windows running in Safe Mode:
1: Reboot Windows in Safe Mode
2. Install the update
3. Reboot Windows
For on how boot your Windows in Safe Mode, please check the guides presented on the following links:

Yes. It might be something related with Parallels, if indeed you are using it.ORIGINAL: Shadrach
If your entire HOME directory (i.e. C:\Users\username) is overridden by Parallels that would complicate things... you'd need to consult the Parallels documentation for this.
