ACR (Adobe Camera RAW) is Built into LR. No need to install it for LR. If you have Photoshop CC 2017 then you need to install ACR 9.8 for that but not for LR.
You have it slightly backwards. If both LR and PS ACR version are the same then LR sends the file directly to PS with all the LR adjustments you made and the RAW file, with the RAW file extension, shows in PS. If the ACR versions are different then LR has to first Render the image and turn it into a TIFF or PSD, as per your option choice in the External Editing section of the LR preferences, and then send it to PS.
Either way LR is applying all the edits you made in LR to the file before it is sent to PS.
If you are getting an error that says something about contacting the System Admin then you have a permissions problem. The folder ACR is trying to install to does not have Write permissions for your user name. Correct that and it should install.
the purpose of installing ACR is to get rid of the annoying nag everytime I export to photoshop. I've had this issue for years, across mutliple OS and systems. seems thats the way it is.
so i update ACR manually to get rid of that nag.
I am the admin to my computer, there are no other users. i can install lightroom 6.8 with no issues, that went fine
but when i try to install ACR simply says update failed. so its not a permissions issue, if one app allows install and another does not, that rules out what you say.
it has to be something else, i google the error and i see it common but i cant find solution to it.
otherwise, how to get rid of the annoying nag message that I must update ACR when i export to photoshop? only way i know is to update ACR which seems to fail.
What specific version of Photoshop are you using (Help / About Photoshop, or PS / About) and what version of Camera Raw is actually installed with PS.
On Windows, you can use Help / About Plug-in / Photoshop.
On a Mac I think there is maybe an Camera Raw / About or Plug-ins / Camera Raw / About. I only have a PC so I’m not sure.
so i tried this:
Hi guys, I've found a solution.
Step 1. Delete or rename the <Startup Disk>/Library/Application Support/Adobe/AAMUpdaterInventory/1.0/AdobeUpdaterAdminPrefs.dat
but does not fix problem.
i try to rename or delete it, it asks me for my password whcih I enter, but than nothing. it wont delete or rename.
ok i figured it out
you cant delete the file in finder directly
you have to move it to the trash can
once in there you have to:
- Open Terminal. It's located in /Applications/Utilities. ...
- Double-click the Trash icon in the Dock to reveal the contents of the Trash. ...
- Press the Command-A key combination to select all files in the Trash.
- Drag the files from the Trash to the Terminal window. ...
- Press Return. ...
- Empty the Trash.
once i did that i ran the update and it worked.
so removing that adobe file worked, so in fact it was an adobe related issue, damn adobe has so many bugs in their updates.
i will pass this along to my friends.
