Is there a way to force Lightroom to use a previous version of Camera Raw?
I'm a very infrequent Lightroom user, prefering Bridge and Photoshop. I have current versions of all installed, but there is a bug in ACR version 8.7, so in Bridge/Photoshop I rolled back to ACR 8.6. That's easy. I just keep old versions of the Camera Raw.8bi files and overwrite a new version with an old version when necessary.
I can't find such a file in the Lightroom folders. I'm assuming the worst, that the ACR code is buried in the main Lightroom.exe and can't be changed, but thought I'd ask anyway.
