Adobe Acrobat Reader crashes every time I open multiple files, it opens the first file fine. However, when i open any more than 1 file it takes around 1 minute to open and begins not responding. I have tried this on 3 different setups on 3 different machines
Hope you are doing well and sorry for the trouble. As described the application is crashing on opening multiple files .
I have tried to reproduce the issue on my end and its working fine? Would you mind sharing the version of the Acrobat Reader DC you are using? To check the version go to Help About Acrobat and make sure you have the latest version 20.12.20048 installed. Go to Help > Check for Updates.
You may also try to repair the installation (Windows Only) Go to Help > Repair Installation and see if that helps.
If it still doesn't work, please try to turn off the protected mode for testing (Windows Only). Go to Edit > Preferences > Enhanced Security > Uncheck 'Enable protected mode at startup', turn off the protected mode and uncheck enhanced security > Click OK and reboot the computer.
Note: Turning off the security may possess security risks. Please turn on the security after testing.
If it still doesn't work, please try o create a new test user profile in Windows or enable the root account in Mac and try using the application their and check.
