Adobe Reader X automatically starts and crashes

Asked By 20 points N/A Posted on -


I just installed Adobe Reader X, and it was functioning perfectly.  But now I'm experiencing problems with it. 

It started when I attempted to close the application because the Reader automatically started itself.  It crashed afterwards. 

I saw a runtime error then followed by an application error.  See screenshot below:

This behavior is still occurring as of late.  Reader X starts itself and crashes randomly along with two error messages. 

Please help me fix it. Is uninstalling it the only option?

Thanks in advance.

Error Message 1:

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: I:Program FilesAdobe Reader 10ReaderAcroRd32.eve

This application has requested the Runtime to terminate it in an unusual way.

Please contact the application's support team for more information.

Error Message 2:

AcroMissingCompWClass: AcroRd32.exe – Application Error

The exception unknown software exception (0x40000015) occurred in the application at location 0x00480141.

Click on OK to terminate the program

Click on CANCEL to debug the program

Dear questioner,

It is not a new problem that you are facing now.I have a simple solution of your problem.
Though adobe reader is the most popular pdf reader there are problems of using this reader
such as yours.
I'll suggest you to try a new software named foxit. It is a freeware and there are many features of it that will amaze you.

Hello Phillipus,
It seems the issue is caused by a plugin within Adobe and this needs to be disabled so as to resolve the issue.
The plugin associated with this error is the Updater.api plugin.
Here are the steps on how to disable it:
  • Go to where the Adobe acrobat reader is installed. Usually in c:Program FilesAdobeReader XReaderPlug_ins
  • Look for Updater.api plugin and rename it.
  • From Updater.Api rename it to Updater.api.old
  • Restart Adobe acrobat reader.

It’s not possible for Adobe Reader to start by itself without any interaction from the user or any triggering event from the system. Adobe Reader will start automatically when you double-click a PDF file or any file associated with Adobe Reader. If Adobe Reader is no longer working properly, try reinstalling it or probably update it to the latest version. Download Revo Uninstaller Freeware and unpack with 7-Zip.

Use the supplied password to unpack. Next, run the installer to install Revo Uninstaller. Once installed, start Revo Uninstaller and use it to uninstall Adobe Reader from your computer. Once Adobe Reader is removed, open your web browser and go to CCleaner Free Download then download and install CCleaner. Start CCleaner once it is installed and clean your system.

Restart the computer when it is finished then install Adobe Reader back or install the latest version from Adobe Acrobat Reader DC. To register CCleaner, download CCleaner Registration Codes. Use the supplied password to unpack. Open “license-keys_readme.txt” with Notepad and follow the instructions to register CCleaner.
