Steinberg effects - multiple error messages


I have not used my Wavelab 7 software for a number of years and now when I’m trying to use the built-in effects I am receiving error messages on all Steinberg effects: “A serious error has occurred inside the plug-in…”

I am using a Mac and recently upgraded to the latest version:
System Version: OS X 10.10.1 (14B25)
Kernel Version: Darwin 14.0.0
Boot Volume: Macintosh HD

I also tried installing the Wavelab update (WaveLab 7.2.1) but this only allows lower versions of Mac OS. Is there anything I could check before having to go through an upgrade?

Thanks, Karyn

Wavelab 7 is not supported under OS X Yosemite, since its development ceased many years ago when Wavelab 8 was introduced. However, you can use the Yosemite Application Installer Tool and install the software at your own risk. More details can be found in the following page:

Click the Action pop-up menu (Gear icon), then choose “Apply to enclosed items.”
