Clean install of Lightroom Classic

[fredf17205859]

MY Lightroom Classic has been running poorer and poorer as time goes by.

To make a very long story, short. This has been plaging me for a very long time.

All I wish to do is uninstall LrC, then do a clean install.

My question is: how do I do this and preserve all of my personal presets, brushes, etc.

[AxelMatt]

First backup all your personal data, like presets and so on.

Infos about that you'll find here: https://www.lightroomqueen.com/backup-lightroom-files/

Then do the clean installation by following the steps below:

• Backup all personal data, like templates, presets, catalog(s) etc. (see above)
• Uninstall everything cc including preferences,   https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html
• Uninstall the cc desktop app,   https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html

• Clean your computer of CC files per  http://www.adobe.com/support/contact/cscleanertool.html
• Restart your computer (don't skip this)

• Reinstall the CC desktop app,   https://www.adobe.com/creativecloud/desktop-app.html
• Use the desktop app to install your cc programs/trials
• Restore your personal data.

If you're unable to install the cc desktop app at this stage, use an administrator account (solution 4 here,   https://helpx.adobe.com/creative-cloud/kb/creative-cloud-missing-damaged.html)

Thank you for your reply. I have been swamped lately and will get back when I can.

[Per Berntsen]

Reinstalling will probably not fix the issues you're having.

Your system info could contain clues about what's wrong, so please go to Help > System info in LrC, click the Copy button and paste in a new reply here.

[fredf17205859]

Thank you for your reply. I have been swamped lately and will get back when I can.
I'll say this for now. The reason I believe a reinstall may work is, I and a friend have tried everything else. Every suggestion I have received during the past several months has been tried without avail. ANd the kicker is, no other image editing software shows the same symptoms at all, EXCEPT LR.

[fredf17205859]

Here ya go.

I do recall doing this once before for someone a long while back. Nothing ever came of it. Hopefully you'll see something.

Make sure you have installed the most up-to-date Studio driver for your GPU. (Game-ready drivers are not recommended for LrC)

Your GPU is 9 years old and this is a likely cause of the slowness you see, as newer versions of LrC are written to make more and more use of the GPU. It is unlikely a re-install of LrC will cause the desired improvement.

[fredf17205859]

?? My PC is 6 1/2 years old.

For approxamatly 4 years there were no issues.

I could run LRC, PS, On1 Photo Raw, and PS Elements concurrently with no issues. Now I find the only way to use LRC without pulling my hair out is to first, reboot the pc, then use LRC only, completing all edits without the benefit of using the others. Then shut LRC down, then use the others. etc, etc 

[dj_paige]

The GPU was first released to the public 9 years ago. It is a slow GPU by today's standards, and that's why it worked well for a few years but now it seems that the actions it needs to perform in LrC take longer and longer. As I said, over the years, LrC has been programmed to use the GPU a lot more to perform standard tasks, leading you to feel that LrC is getting slower. You need a newer GPU.

[Per Berntsen]

Your GPU driver is 12 months old.

I agree with @dj_paige that your GPU might be too old to perform well with LrC, but updating the driver might help a bit.

Download the latest studio driver from here: https://www.nvidia.com/en-us/drivers/details/245675/

You also have an integrated GPU – UHD Graphics 630.

Make sure that it is disabled, LrC does not work well with dual GPUs.

Go to Control panel > Device manager > Display adapters. If the UHD Graphics 630 is enabled, right click it and choose Disable.

[fredf17205859]

The driver is only 12 months old as someone suggested updating it a year ago to solve my issues. The update  didn't help at all. I'll mnow have a look at your suggested disabling of integrated GPU.

Thanks. I hope.

[fredf17205859]

OK. It looks like you may be on to something.

After the disable, LRC startup time (the time it took to turn control over to me) was 41 sec. It hasn't been under a minute or more for a very long time.

Create Mask: The first one was instantaneous

Creat New Mask: Time it took was 17 seconds. Way slower than in any instructional video, but much improved over my previous times.

I then updated the nvidia driver and saw a difference when I rebooted. Things are seemingly jumping into place quicker than before. Of course  the real test will be my next full editing session. I'll get back to you on that. Thank you. Hopefully I'll see even better things once I'm in gear.

Fred

[dj_paige]

All I wish to do is uninstall LrC, then do a clean install.

This is unlikely to help slowness, as stated by @Per Berntsen . Please provide the system information that was requested.

Also please be specific, what actions in LrC are slow?

[fredf17205859]

Would you believe ALL ?

From startup times as long as 3-4 minutes, or longer. I sometimes can literally go make coffee while waiting for LR to become usable. Or how about this one: Grab a brush, pick a color, whatever, drag the brush across the image, then sit back and wait for it to slowly draw, or, one more create a mask, make it a brush whatever, doesn't matter, then when creating another mask, go use the bathroom while the image flickers, changes colors, goes through all kinds of gyrations befor it finally puts the new mask up. Not your usual day to day expectations. I have a short video showing one anomalie, but seems there is no way to post it here. If I'm missing something, and it can, let me know. I think I still have it.
Thanks

[Per Berntsen]

If you want help, please post your system info as I requested above.

It contains lots of information about your computer and your LrC configuration, and is an invaluable tool for troubleshooting.

We get quite a few posts from people having issues similar to yours, and I'd say that more than half of them are solved by means of the system info. Reinstalling rarely fixes anything.

If you're replying by email, you cannot post images and videos, you have to use a web browser to do that.

Please do not attach images, use the Insert Photos button in the toolbar to embed them in your post.

The button to insert videos is right next to it.

[CAR141]

I didn't read all replies but have you made sure your hard drive with LR catalog etc. isn't almost full. 

[fredf17205859]

Yes. Absolutely.

Thanks
