If the SI dlls are not installed you can either try reinstalling using the registry edit mentioned above or use the X1 installer. If you prefer not installing the X1 DAW, run the X1 installer, selected 64bit, select advanced install, then pick the plug-ins to install.
I think the above will be the route I want to take, since I did install the 64 bit version. I'm not the most tech savvy and don't have experience with reg editing so I will have to get my son in law to assist.
Not quite sure I understand this:" If you prefer not installing the X1 DAW, run the X1 installer, selected 64bit, select advanced install, then pick the plug-ins to install ." Are you saying I can run the the installer from Bandlab Assistantand choose advanced install? Would I have to uninstall first?
Thanks for your help.
