Hello Evert-Jan,
Thanks for helping the Dutch forum user. Do you know whether he/she had installed the current version of iLok License Manager prior to trying to run Hauptwerk v5?
(I believe that the Visual C++ runtime should only be needed by PACE's components, and I think iLok Licence Manager's installer installs them. The Hauptwerk installation prerequisites do state that iLok Licese Manager should be be installed first.)
Thanks again.
