Over the years I have many generations of audio software and plugins installed on Windows, which itself has gone through many version upgrades. I can't remember why but one upgrade called for changing the system drive from C: to K: (probably for a backup reason), and ever since then K: has been my system drive.
Between projects, I decided to give Sibelius 8 a try. However, the installation file (Install_Sibelius.exe, unpacked from Sibelius_8.0.0_Win.zip) downloaded from Avid gave me this error:
Error 1327 invalid drive C:\.
By inspecting the log, I concluded that was hard-coded in the installer (FAIL! To tell the truth, it has been a familiar feeling ever since Avid acquired Sibelius).
I really don't want to change the system drive again, since it would involve the painful process of re-configuring a million things. It's also after their support hours so I did some research, and after some trial and error, this is what worked for me:
1. run cmd.exe as Administrator.
2. Change into the directory where Install_Sibelius.exe resides
3. Run the following command
J:\Users\composer\Desktop>J:\Install_Sibelius.exe /s /v"/qn /l*v %temp%\AvidSibeliusx64.log"
4. Follow the standard procedure to activate the software
PS: I very much look forward to Daniel Spreadbury's new score writer.
