DMP Troubleshooting


Issues Opening DMP Files

Missing Microsoft Visual Studio

When trying to open your DMP file, you get the error "Can't Open DMP File Type". Usually, this is because you do not have Microsoft Visual Studio for %%os%% installed. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.


Tip: When another DMP application is installed, you can choose to open it by selecting "Show Apps" and using that program.


Wrong Version of Microsoft Visual Studio is Installed

In some cases, you might have a newer (or older) version of a Windows Memory Dump File file that is unsupported by your installed application version. If you've got the wrong version of Microsoft Visual Studio installed, you'll need to install the correct version. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.


Tip: Find clues on the correct software version by right-clicking your DMP file and clicking "Properties".


Summary: Not having the right Microsoft Visual Studio version on your computer can cause problems opening DMP files.


Other DMP File Opening Causes

You can still experience errors opening DMP files even with the latest version of Microsoft Visual Studio installed on your PC. If you're still experiencing problems opening DMP files, there could be other computer problems. Problems unrelated to software:

  • File references in the Windows Registry for DMP are wrong
  • Deletion of the DMP file description from the Registry by mistake
  • Partial installation of Microsoft Visual Studio that did not fully complete
  • Something has caused file corruption of your DMP
  • Your DMP has adversely impacted by malware
  • Device drivers of the hardware associated with your DMP file are corrupt or out-of-date
  • Too many applications are open on your PC to load your Windows Memory Dump File file successfully
