Hi ! Best wishes to everyone at the LUG community! My year hasn't started too brillantly though: although "gone Mac" last year, I still use a PC with Logic Audio Silver 4.6 (upgraded to 4.8) for my older projects that won't play in Logic Pro. I just purchased a faster PC with OS Windows 7. As I try to install Logic 4.6 on it I encounter several problems: The first installation was ok, it ran with glitches and noises but that was without tweaking the system. 2 days later Logic suddenly stopped and computer displayed: "this program is not working anymore. Please re-install or contact the supplier..." The first attempt to re-install error'ed out, saying it couldn't find a certain .dll bit. The second up to the 5th attempt displayed "Cannot read files, CD-ROM is damaged" (checking on an other PC showed it is just fine). The last attempts all ended up with the message "Due to your internet security settings one or more files cannot be opened". This is with Windows Firewall, Defender and Anti-Virus programs all switched off! I have no idea on how to proceed from this point. My specs are: processor Intel Core 2 Duo CPU T7500 2 Gb RAM 64 bit operating system Can anybody help me out? Thanks a million !
