You don't need ACR if you have Lightroom. It's built into Lightroom.
Lightroom 1.1 uses the same engine as ACR 4.1.
If you installed ACR 4.1 into Photoshop, you can reinstall Photoshop to go back to 4.0.
There is a very long, heated discussion about 4,1 here:

Hi Ramon, thank you for your reply. I have CS2 and CS3 upgrade. Do I have to reinstall both softwares? Thanks for the link, but I have been following this thread for quite a while. I must be one of the many other photographers who noticed 4.1 bad image rendering and did not speak up.
> have CS2 and CS3 upgrade. Do I have to reinstall both softwares?
No. ACR 4.1 would only have been installed in CS3, as ACR 4.1 does NOT work with CS2.
The latest version that can be used with CS2 is ACR 3.7.
Presumably you want to downgrade to ACR 4.0 in Photoshop 10 ("CS3") and you can do that in one of two ways: (1) by reinstalling Photoshop CS3, or (2) if you have a backup copy or otherwise have access to a copy of ACR 4.0, you can just replace ACR 4.1 with ACR 4.0 manually.
> I have CS2 and CS3 upgrade ...
Hmmm(?) ... how would the Adobe directory, which should be common to CS2 & CS3, accommodate 2 versions of ACR?
Michael: <br /> <br /> Don't know about Windoze, but on the Mac that is not a problem at all. <br /> <br />c <a href="http://www.pixentral.com/show.php?picture=1kOhVDh5yzAU0Xb5LHZOSjsAPDjqI" /></a> <img alt="Picture hosted by Pixentral" src="http://www.pixentral.com/hosted/1kOhVDh5yzAU0Xb5LHZOSjsAPDjqI_thumb.jpg" border="0" /> <br /> <br /> The install path for ACR in Photoshop 7 and 8 is entirely different from the above. So you can have all four iterations of ACR installed, one for each version of Photoshop. <br /> <br /> I keep Photoshop 7.0.1, 8, 9.0.2 and 10 installed. I can even run more than one version of Photoshop at once, I just have to start the older version first.
Actually, the Adobe directory has separate subdirectories for each version. I have CS2 and CS3 both on my computer at home. Using windows XP.
Thanks for the confirmation, Jim. I would have been surprised if that wasn't the case, but I'm too far removed from Windows to know for sure.
