Would suggest you to make sure the following list of folders have full read and write permissions and then, relaunch Lightroom to check :
C:\Program Files\Common Files\Adobe*
C:\Documents and Settings\<user_name>\Application Data\Adobe*
C:\Documents and Settings\<user_name>\Application Data\com.adobe.*
C:\Documents and Settings\All Users\Application Data\Adobe*
C:\Documents and Settings\<user_name>\Local Settings\Application Data\Adobe
You need to follow below steps for each of these Adobe folders :
- Right click on the folder > Properties
- Go to Security tab > edit
- Choose Add
- Type everyone > click on OK
- Check mark under Allow for Full control
- Click on Apply > OK
Here is the list of folders :
C:\Program Files\Common Files\Adobe*
C:\Program Files (x86)\Adobe*
C:\Program Files (x86)\Common Files\Adobe*
*Appdata folder is hidden by default
you can press windows and r keys to open run window and type in appdata.
THANKS again for your speedy assistance - I will try this right now and let you know!
When I try your suggestions for C:\Program Files (x86)\Adobe I get the following error message:
"An error occurred when applying security info to: C"\Program Files (x86)\Adobe\Acrobat Reader DC\Re....\CMap" -- "Failed to enumerate objects in the container. Access is denied."
Should I not be doing this for " C:\Program Files (x86)\Adobe ????
You need to right click on these Adobe folders and give permissions.
If you receive this sort of error on any of the folder, you can choose to skip that part.
Doing what you suggested did not help at all....the EDIT-Preference dialog box still does not appear! I did what you said for all the folders except the (x86) two folders AND I do not have the folder
I also meant to say in my previous "reply" that before today the EDIT-Preferences dialog box has always appeared......I don't understand why, all of a sudden, It chooses to not display as usual?????
- Hold windows + R at the same time
- Type temp , click ok
- Now select all files in there and delete them
- Repeat the same step for %temp%
- Restart the computer
- Now go ahead and update graphics card drivers.
- Restart your computer and then check again
Your instructions are too brief! I don't have a clue as to what you mean! Also, the EDIT-Preferences dialog box has always appeared so I don't know why I would have to go into any of these instructions???? Can anyone please tell me why the dialog box would just stop appearing?
There can be many reasons why it is not opening
- Temporary files on your computer messing with Lightroom
- Obsolete graphics card drivers.
Let me explain the steps again.
- On your keyboard you have a Windows key, hold it down, and at the same time hold R key
- Windows + R key at the same time.
- Now a small run box will appear, remove everything written in there, and then type %temp%, click ok
- Delete all the files that you see in this folder
- Repeat the above steps for temp, and empty temp folder as well
- You have to delete file from both folders, %temp% and temp
- Restart your computer
- Now go to the manufacturers website and update your graphics card drivers
- Download the file and then double click on it, and wait for the installation to complete
- Once the installation is complete, the software will automatically check for the updated version of Graphics drivers, you just need to follow the instructions mentioned in there to install it.
- Once done, then restart your computer.
Now use LR and see if it is working fine, are you able to open preferences.
If you are still not able to follow the instructions would suggest you to contact customer care - Contact Customer Care
Well, I have done what you suggested above, including updating the Nvidia driver, to no avail......I still cannot see the "Edit-Preferences" dialog box!
I guess I will try contacting Customer Care to see if they can assist me.
Thanks for the update.
Would suggest you to try the following steps as well :
- Quit Lightroom
- Choose Control Panel > Region & Language > Additional Settings > Numbers > Digit Grouping.
- Change the number format from 123456789 to any other format (for example, 123,456,789).
- Click Apply > OK.
- Open Lightroom.
- Choose Edit > Preferences.
Chetna, that setting is already set at 123,456,789.
Let me ask you this .... I have the original disk for Lightroom 6. I am thinking that I will just re-install it from my disk. My questions about reinstalling Lightroom are:
What will happen to all my catalogs? Do I need to back them up or will they still be there on my computer?
What will happen to all my installed filter collections? Will I have to re-install them?
I still do not understand WHY this problem occurred in the first place?????
Not sure why is it doing so.
Uninstalling would not affect your catalogs and collections.
Your Lightroom catalogs would remain intact with all edits and collections.
Still you should take a backup of your catalog.
You can reinstall Lightroom 6
Here is the download link : Download Photoshop Lightroom
I am still not able to see the dialog box when I select EDIT-Preferences. I have followed all your instructions above and as a last resort I removed Lightroom 6 through the Control Panel and then reinstalled it.......this did not help at all. I seem to be able to open all the other dialog boxes in the EDIT command, except PREFERENCES and CATALOG SETTINGS. When I try to select those two no dialog box opens up!
Can you please think of anything else I can do to correct this situation?
Two more things to try:
A. Reset LR's preferences, as described in this article: Resetting the lightroom preferences file - updated - Lightroom Forums. LR not infrequently soils its preferences file, and when it does, it behaves unpredictably. (The preferences are not reset when you reinstall LR.)
B. Manually edit the preferences file to disable LR's use of the graphics processor, as described in this help article: Adobe Photoshop Lightroom Help | Lightroom Graphics Processor Acceleration (GPU) Troubleshooting & FAQ. A little more detail on the steps outlined in that article:
- Exit Lightroom.
- Click on the Windows Start button in the lower-left corner, and copy and paste "%appdata%\Adobe\Lightroom\Preferences\Lightroom 6 Preferences.agprefs" (without the quotes) into search box, then type Enter. This will open the preferences file in Notepad.
- Change the following line: useAutoBahn = true to the following useAutoBahn = false
- Do File > Save followed by File > Exit.
- Launch Lightroom CC/6 again
Chetna Srivastava, you will not believe it BUT JUST THIS MINUTE I SOLVED MY PROBLEM BY USING THE INFO THAT johnrellis SUPPLIED IN THE ABOVE CHAT BOX! I can now open the EDIT - PREFERENCES and the EDIT _ Catalog dialog boxes!!!! I am so happy and I do hope that I have actually solved my problem. What I did was I moved the "Lightroom 6 Preferences.agprefs" file from one location and then put it back there..... does this make any sense to you? I still don't understand what happened because I have never manipulated this file in any manner before....but I am happy that it seems solved for the minutes.
If you would like to look at my system to see if all is okay ....
I do really appreciate your assistance!
I followed your instructions in the two articles below and it seems to have solved my problem! I AM SO HAPPY!!!
I have spent several hours, over 2-3 days, reading and trying to solve this problem …. I really appreciate the help you and Chetna have provided.
THANKS a bunch!
I hope I don’t have to bother you again.
