You will need to install M-Crew on the new computer.
It is only available on the supplied CD with the Sony HCD-C7NT.7
-Windows XP (Home/Pro): DriverXP folder -Windows 2000: Driver2000 folder -Windows 98 (SE)/Me: Driver folder
I have tried installing it and it dd not run, so I uninstalled and tried again, still would not run. Both times froim the original installatuion CD but the read.me shows that it is for the following systens
It is quite an old software, designed for those systems, so it may not be compatible with your latest Windows 8.1 computer.
Are there any unpdated drivers to make it work in 8.1?
There are no updates or newer versions of the software available.
Unfortunately not - Sony did not expect these systems to be around for more than a few years.Your system is one of probably only a few still in existence, so they have not had enough demand to warrant any ongoing support for these systems.
According to my manual I bought it in 2003 and it has been brilliant. That is a real shame. OK, thanks
Have a good weekend!
