Whan selecting "Edit in" option to edit a DNG in Photoshop CS4, I get the prompt, "This version of Lightroom may require the Photoshop Camera Raw plug-in v. 6.4.1 for full compatibility. Please update the Camera Raw plug-in using the update tool available in the Photoshop help menu".
I carried out that update, but the prompt continues.
I have LR v. 3.4.1 installed, and the "About" screen shows that ACR 6.4.1 has been installed.
I have PS CS4 v. 11.0.2 installed. PS Plugins display shows ACR 5.7.0.213, despite my having downloaded and installed 6.4.1. On selecting Help | Update, I'm getting the message, "There are no updates available at this time".
It appears that ACR 6.4.1 did not get installed into PS CS4. Just to be sure, I again closed both LR and PS and installed the plug-in. Installation took less than a second. PS "About | Plug-ins | ACR" screen is unchanged.
Is there a way that I can force ththe installation to happen?
ACR 6.4.1 does not work with CS4. See this list:http://kb2.adobe.com/cps/408/kb408941.html
