PSE is showing CR7.4 as the version it's using. Why won't it update?
To use ACR 8.7 you’ll need PSE13 and would need to wait until the ACR 8.7 Final is released because the RC is only ever for Photoshop, not Elements.
However, you can edit new camera files by downloading the DNG Converter 8.7 RC from the same place and using it to convert your raw files to DNGs then those DNGs will open in an older PSE/ACR combo.
