(Win 10) Lightroom v5.5 doesn't open - App unable to start correctly (0xc0000005)

Question

I am having the same issue suddenly when trying to open Lightroom from Windows 10.   When attempting to open LR from the Creative Cloud Desktop, nothing happens at all.  When I try to open LR through the app on the computer itself, I get the following error prompt: 
 
Lightroom.exe - Application Error
App unable to start correctly (0xc0000005)

I also have Photoshop installed on the same computer.  I can open Photoshop from the app or through the Creative Cloud Desktop with no issues at all.  I can also open Bridge through the Creative Cloud with no issues.  
 
This appears to be a LR only issue.

I've separated your response as a new thread on its own, as it is a different issue.

Please try these steps & let me know how it goes.

In the Creative Cloud app, press CTRL + ALT + T (Win) to launch Creative Cloud Troubleshooter & select 'Close Creative Cloud and related processes' > click on Go.
Go to 'Add or Remove programs' in Windows search & find all the installations of Microsoft Visual C++ Redistributable (all years).
Uninstall them completely. Even if there is an option to repair them, please uninstall all the existing MSVC++ packages.
Download a fresh package of installers for MSVC++ from this link. https://adobe.ly/3DkgAVF
Right-click the downloaded file and select Extract All.
Reinstall all packages (32bit & 64bit) & then restart the computer.

Let me know how it goes from here. Thanks!
