opening cadtools forces to install Navisworks

[Robing]

Hello,

A colleage of mine has a problem when opening Cadtools.
Every time he opens Cadtools, the installation progress of Autodesk Navisworks starts to run.
He has to wait a few minutes before being able to cancel the installation progress, and than Cadtools opens.

Is this a known issue?

I've never heard of it with CadTools although I've ran into this problem before with other software. Probably there are something wrong with the NavisWorks installation. A repair might solve the problem.
