Windows8でフリーズする

Hi there

Hope you are doing well and sorry for the trouble. As described, the Acrobat Reader freezes when opening PDF.

Would you mind sharing the version of the Adobe Acrobat Reader DC you are using? To check the version go to Help > About Acrobat and make sure you have the latest version 21.01.20149. Go to Help > Check for Updates and reboot the computer once.

If the PDF file stored on a shared network/drive please download and save it to your computer locally and then try to open it and check.

Please try to turn off the protected mode for testing (Win Only) and see if that helps. Go to Edit > Preferences > Enhanced Security > Uncheck 'enable protected mode at start up' Turn off the Protected mode and Uncheck 'Enhanced Security' > Click OK and reboot the computer

Note: Please turn on the security after testing to avoid any security risk.

You may also check out the steps provided in the help page https://helpx.adobe.com/x-productkb/global/troubleshoot-system-errors-freezes-windows.html and see if that helps.
