CSN File Complications


Frequent CSN Opening Issues

Adobe Dreamweaver Not Present

When trying to open your CSN file, you get the error "Can't Open CSN File Type". Generally, this is experienced in %%os%% because Adobe Dreamweaver isn't installed on your PC. You won't be able to double-click to open your CSN because your OS doesn't know what to do with it.


Tip: If you have another software that you know opens CSN files, you can select it by hitting the "Show Apps" button.


Adobe Dreamweaver is Out-of-Date

In some cases, you might have a newer (or older) version of a Adobe Code Snippet Document file that is unsupported by your installed application version. Visit the Adobe Systems Incorporated website to download (or purchase) the latest version of Adobe Dreamweaver. The primary cause of this problem is that your Adobe Code Snippet Document file was created by a different (newer) version of Adobe Dreamweaver than what's installed.


Tip: If you right-click on your CSN file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.


Primarily, problems experienced when opening CSN files are due to having the incorrect version of Adobe Dreamweaver installed on your computer.


Other Causes of CSN File Opening Problems

Even with the correct version of Adobe Dreamweaver installed, you can still experience difficulties opening CSNs. Other CSN opening errors can be created by other system problems inside of %%os%%. Additional factors include:

  • Invalid CSN file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • Deletion of the CSN file description from the Registry by mistake
  • Invalid installation of a CSN-associated program (eg. Adobe Dreamweaver)
  • CSN file corruption
  • Malware-tainted CSN file can't be opened
  • Device drivers of the hardware associated with your CSN file are corrupt or out-of-date
  • Your computer does not have the adequate system resources to open the Adobe Code Snippet Document format
