Problem installing Trueview 2011 x64

Hi everyone!
I tried installing Trueview 2011 x64 and got stuck at the registration part. I have no idea what seems to be causing the problem, the only thing I get is this error message:
Installer Information
Erreur 1904. Le module C:Prpgram Files(x86)DWG TrueView2011acctrl.dll n’a pu enregister. HRESULT -2147010895 contactez votre support.
Abort Retry Ignore

I’m using Windows 7, so if anyone had a similar problem in the past please let me know so I can try and fix this.
Thank you very much.
