There have been a couple of threads in the Digidesign User Conference and the problem has been traced to an incompatibility with iZotope plug-ins and Pro Tools 8.0.4. In this thread ‘subwoof’ asked….
I just spent 90 minutes with Digi (Avid) only to be told there is an “issue” popping up with 8.0.4 and Audio Suite. On my system, I am getting -7453 errors when trying to preview. On some plugins like Pitch N’ Time Pro and Izotope RX, they simply don’t preview, and then they render out a blank file. Some of the Digi plug ins work, but I get an “Access Violation” error, and sometimes Pro Tools just quits.
I sent in the error log to them, and they are going over it. In the mean time, they told me to go back to 8.0.3 cs2. They also recommended that my colleagues here in town not go to 8.0.4 yet until they do more research into Audio Suite issues.
It may work for you, but have your 8.0 installer disc handy just in cast you need to regress!!
‘SessionKat’ otherwise known as Tim vdB – Digidesign Engineering suggested…
Its likely this is dependent on some 3rd party component(s), as many of us in-house and others can not reproduce unless we have IZotope Audiosuite installed…
Then DGould – David Gould – Product Manager – Audio Post Production – Avid confirmed…
We have discovered a problem with 8.0.4 specifically to do with -7453 errors when previewing iZotope AudioSuite plug-ins. We have today posted a warning about it on the download pages. Thank you for helping to bring it to our attention.
We suggest that iZotope users remain on 8.0.3cs2 until this issue is resolved. At time of writing it is our understanding that this issue only affects users with iZotope plug-ins installed (even if the problem is manifesting itself with other plug-ins). We will provide an update as soon as we have more information.
So there it is iZotope users should say on 8.0.3 or lower until iZotope release an update that is compatible with 8.0.4
