App Crash

Hi Naveenl48052992

We apologize for the delay in response.

When exactly the application is crashing? during launch of Adobe Reader or when you are trying to make any changes in the document?

Please confirm the exact dot version of Reader and operating system whether its mac or windows computer that you are using?

kindly refer to Resolve Acrobat DC intermittent crashes on Windows OS

you may also refer to Troubleshoot errors, freezes | Adobe Reader | Windows  if you are experiencing any specific error message.

Thanks,

Akanchha
