in my case it seems that the cd was broken. the installation was successfull, but i had a lot of bugs. for example couldn't open the library. but the disc itself was running smooth (i think it just didn't install the part with the library or something?)
nevertheless, i downloaded the install.exe from arturia-homepage, de-installed spark and installed it again with the exe i downloaded (V1.7.1) since that i have no problems and everything works fine.
