Adobe released the all new Lightroom CC (the cloud-based photo service), Adobe Photoshop CC version 19 and Lightroom Classic CC (the desktop-focused photo editing software) in October, 2018. I could easily upgrade the apps on one Windows 10 computer, but my main desktop (also running Windows 10) could not detect the updates at all. I uninstalled both Photoshop and Lightroom and reinstalled them, repaired/uninstalled-reinstalled Adobe Creative Cloud app, even used the Adobe Cleanup Tool, but nothing helped. I even uninstalled all Adobe apps, deleted all Adobe-related folders and cleaned registry of all Adobe entries. Still nothing, just Creative Cloud suddenly began to pop up two User Account Control prompts instead of one after logging in.
Adobe’s forums have many entries from people with the same problem, no working fixes have been posted. Tonight, I had enough of it. Hey, every Creative Cloud subscriber should be able to see and install the new apps! I kind of knew it had something to do with either Windows 10 version or some anti-virus app. My laptop with the successful Adobe apps upgrade is still running Windows 10 Creators Update (version 1703), but my desktop has the latest version of Windows 10, the Fall Creators Update (version 1709).
To check Windows 10 version number, open Start, type winver and click the result.
I am also working on an update to the Windows Defender Security Center tutorial for Windows 10’s Fall Creators Update. You see, the latest version has something called Exploit Protection (previously available as a separate software called Microsoft EMET). Because EMET has had its fair share of problems with enforcing system-wide exploit prevention techniques (such as web browsers crashing or not opening), I decided to try out disabling Exploit Protection for the Adobe Creative Cloud app. And it worked – I now have the latest Photoshop and Lightroom Classic CC versions on both of my devices! 🙂
Please do note that the latest Creative Cloud apps cannot be installed in Windows 7 without Service Pack 1 and in the original release of Windows 10 (versions 1511 and up are supported as of 2017-10-30).
The new cloud-based Lightroom CC works only in Windows 10 version 1511 and newer, older Windows versions are not supported. You can, however, run Lightroom Classic CC in Windows 7 SP1 and in Windows 8.1.
Also, only 64-bit Windows is supported.
Latest data on Adobe Lightroom Classic system requirements is available at https://helpx.adobe.com/lightroom/system-requirements.html
To resolve the inability to see or install Lightroom CC, Lightroom Classic CC and Photoshop CC in Windows 10 Fall Creators Update, open Windows Defender Security Center by opening Start, typing defender and clicking or tapping Windows Defender Security Center in the results.
Next, open the App & browser control tab, scroll down to the Exploit protection section and click or touch the Exploit protection settings link.
Open the Program settings tab from the top, hit the Add program to customize button and select the Choose exact file path option.
On 64-bit Windows 10, navigate to the C:\Program Files (x86)\Adobe\Adobe Creative Cloud\ACC\ folder. Please do note that the latest Creative Cloud apps do not run on 32-bit Windows anymore.
Click or touch the Creative Cloud.exe (or just Creative Cloud if the displaying of file extensions has been disabled) file and click Open.
In the Program settings: Creative Cloud.exe pop-up, tick the Override system settings check box and set all sliders to the Off position. There should be 21 different exploit prevention techniques there.
Yes, this will make Creative Cloud a bit more vulnerable to zero-day exploits, but at least you will be able to use it as Adobe intended and as you all expect.
I’m sure someone has enough time to test which exact exploit protection causes the inability to install or update Lightroom Classic CC in Windows 10. 😉
Finally, click or tap Apply and restart the Creative Cloud app (right-click or touch and hold its icon in Taskbar Notification area, choose Quit; then relaunch it from Start menu) – or just restart your device.
After this, you should be able to see and install the brand new Lightroom CC, Adobe Photoshop CC and Lightroom Classic CC apps even in Windows 10 Fall Creators Update.
You’re welcome and thanks for reading!
