How to downgrade to Compressor 4.0.7

So I have been following the threads on Compressor 4.1 and it's limitations on instances. I have an iMac from 2012 and I can't get multiple cores working for me. Very frustrating! It took me a bit to get it working with version 4 in the first place, so I'm peeved.

Anyways, I have time machine backup from before the update and I'm wondering if this is a simple switch of the application? Surely there were lots of other changes to the application during that last update to 4.1. So...

Is there a link where I can download a version 4.0.7 install? I can't find older versions on apple's site anywhere.

iMac, OS X Mavericks (10.9), 3T Fusion, 16GigRAM, 2Gig-680MX

Yes you can use Time Machine to install Compressor 4.0.7. First you need to uninstall 4.1. Use this free app to uninstall Compressor.

Apple has gone a different way in 4.1 to speed up encoding (with/using Hardware Acceleration)... read this:

Some of us have done some testing... read this:

Thanks for the links. I have seen this other thread. In reading things closer it looks like it might be my usual use of multi-pass encoding. After turning that off my i7 imac seems to encode faster. So I'll work and test with that for now.

It is still not using multiple threads or "instances" though, and there will be times when I want to do a multi-pass encode. I do have a new multi-core i7, so I thought I would still have that option? Any thoughts on that?

If I decide to downgrade, would I need to simply enter time macnine and 'restore' the app. in the applications folder? Surely there are support files?

Your help is appreciated!

So it seems like my iMac started to do multi-thread encoding, with the Multi-pass encoding turned on. It seemed to split the job into 3 video streams and 3 audio streams. I didn't change a thing which is confusing, as it wasn't doing that before. Both times it was encoding to H264, which according to Larry Jordan's article, would be Hardware Accelerated. So...
