I appear to have the exact same issue as the OP. I have a Windows 11 computer that refused to launch any of the newer Adobe apps (2025 Premiere and Audition, the betas, and InDesign 2026 when that was made available). Since my career is working in InDesign, and I work in a team, I had to fix the issue, so I had my IT department completely reset my computer. Wiped it all, started clean with a new installation of Windows, and when I installed Creative Cloud desktop, it now loads with the error 502 unable to update. I was able to install the apps I needed, but still had the failure to launch on most of the newer ones. After a lot of back and forthing with ChatGPT, we discovered that installing the Microsoft Visual C++ Runtimes fixed the launch issue, and I'm now running all the apps I need. However, the Creative Cloud Desktop app is still throwing the 502 error and is unable to update. It's said that since the clean install. Technically, we have already tried the uninstall and run the cleaner, etc. because we installed it on a clean harddive after a reset of everything, so I share the OP's frustration. Is this a compatibility issue between CC and Windows 11? Is it a problem that the desktop app cannot update? Will that cause functionality issues in the near future?
