Halion Sonic Se error 1603

Well i just bought Cubase 6.5 for Halion Sonic Se to use with the symphonic orchestra , BUT…
For the 64 or 32 bit installation of Cubase 6.5 i do get the same error : HAlion Sonic Se content installation failed error code 1603/1610
I install cubase not on the rootdisk where windows 7 is installed( C: ), but on disk E:
There we are… brandnew software and not to install…frustrating.
How to solve this issue ?
