Photoshop.exe Error: Entry point not found

Another idea is a complete and clean reinstallation.

Please follow the steps below:

• Backup all personal data, like templates, presets etc.
• Uninstall everything cc including preferences,    https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html
• Then 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)

Unfortunately you haven't given us any information about your system. Therefore, all proposed solutions are a look into the crystal ball.

Is your system up-to-date? Do you have installed all recent updates and patches for the operating system and the device drivers, especially the graphic driver. If you have a NVidia graphic card installed, make sure that you are using the recent Studio version of the driver, not the Game Ready version.

Download and install the latest supported Visual C ++ Redistributable Packages for Visual Studio 2015, 2017, 2019 and 2022 from the Microsoft website.
