Would suggest you to refer this link and repair/update Microsoft Visual C++ 2012 Update 4 and then, check : Download Visual C++ Redistributable for Visual Studio 2012 Update 4 from Official Microsoft Download Center
OK; but if I do this is there any guarantee it won't compromise something else? Sorry to sound like I am a wimp but I am a software user, not at all an IT expert.
Yes, sure it would not affect anything else.
This Visual C++ setup is required to run certain programs.
OK thanks Chetna - I'll try it. One question (and thanks for your prompt responses): there are three exe files mentioned and I get the impression that once I start the process I am going to be asked which file I need. Which file do I need?
You need to download x64.exe file and run it to install > choose repair/install.
Once done, restart machine and then, try to open Lightroom.
No, this didn't work. Just to tell you what Lightroom looks like through all this: I have the grey panel with Library/Develop etc across the top, but nothing in the grey panel. When I click the mouse anywhere I get the rotating blue circle of death. When I try to shut down it tells me Lr is not responding.
Thanks for the update.
This seems to be due to graphics processor.
I would suggest you to follow the below steps mentioned here to turn off GPU in Lightroom :
- Force quit Lightroom through task manager.
- Navigate to %appdata%\Adobe\Lightroom\Preferences\Lightroom 6 Preferences.agprefs.
appdata would be hidden by default. So, press windows and r keys to open run window and type %appdata%.
- Open the file Lightroom 6 Preferences.agprefs in Notepad.
- Change the line useAutoBahn = true to this line: useAutoBahn = false
- Save and close the file Lightroom 6 Preferences.agprefs.
- Launch Lightroom again and check if it works fine.
No, this didn’t work either.
What if you right click on Lightroom icon and choose run as an administrator?
Does it work better?
Same, thing, grey screen, blue circle of death and a note that Lightroom is not Responding.
Go to Control Panel >> Open Device Manager >> Look for Display Adapters >> Under that you will find the listed Graphics Processor
Right Click on it and disable it.
Once done, Open Lightroom and check if that works fine.
If it works fine, then disable the Graphics Processor from the Lightroom Preferences by going under the Performance tab and Uncheck the Graphics Processor.
Close Lightroom, enable the Graphics Processor from the Device manager and try using Lightroom.
I had the same problem for a few days. Tried everything mentioned in this line.
Finally I decided to try log on to Adobe Creative Cloud.
Now everything works again.
Hope it works for you.
Chetna, is this site safe? When I tried downloading the Lr 6.4 update I ended up on a site saying (a) I had to purchase WinZip at a cost of ~$35, and (b) they’d be billing me at intervals for more money. Is there another way I can get the update without having to spend money for a one-time product entailing dubious annual subscriptions?
Mohit, this didn't work for me (apart from being thoroughly frightening to implement!)
Well done, you nailed it! How odd that no-one in Adobe should have thought of this. I have stand-alone Lr 6 and I've been getting start-up messages to sign on to Adobe Creative Cloud long before I updated to Win 10. I ignored them because as far as I was concerned Adobe CC referred solely to the monthly-subscription PhotoShop CC/Lightroom package that I decided I could do without. (And truth to tell, I really had no clear idea what they were talking about.) So all of this may have had nothing to do with Win 10 at all.
I do not know how you discovered this but a thousand thanks for sharing it.
Nope...that didn't work! I have the same problem and your solution to change use autobahn to false did nothing to help.
any other suggestions?
Did you follow the other suggestions mentioned in this same thread ?
