Uninstalling Lansweeper 3.2

[CCadog]

I am trying to uninstall Lansweeper 3.2 but keep receiving an error. The error is

Runtime error (at 158:3408):

Failed to open Microsoft IIS.

(Error ':' occurred)

This appears at the Uninstalling Lansweeper WebConsole step.

What does this error mean?

I have no idea, never seen it before.
To manually uninstall it, open the IIS configuration and delete the lansweeper32 virtual directory.
