Sources of SDN Problems

Common Problems Opening SDN Files

Missing ARJ Software JAR

When trying to open your SDN file, you get the error "Can't Open SDN File Type". Usually, this is because you do not have ARJ Software JAR for %%os%% installed. The typical path of opening your SDN with a double-click won't work because %%os%% cannot make the program connection.

Tip: If you know of another program that can open your SDN file, you can try opening it by selecting the application from the programs listed.

Incorrect ARJ Software JAR Version

In other instances, your Shareware Distributors Network File file version may not be supported by your version of ARJ Software JAR. If you've got the wrong version of ARJ Software JAR installed, you'll need to install the correct version. This issue mainly occurs when your Shareware Distributors Network File file was created by a newer version of ARJ Software JAR than you have on your PC.

Tip: Investigate your SDN file by right-clicking and selecting "Properties" to find clues on what version you need.

Primarily, problems experienced when opening SDN files are due to having the incorrect version of ARJ Software JAR installed on your computer.

Other SDN File Issues

Assuming you have the right ARJ Software JAR version installed, other problems can prevent you from opening SDN files. There can be other issues - unrelated to software - preventing you from opening SDN files. Issues that aren't software-related:

• File references in the Windows Registry for SDN are wrong
• Accidental deletion of the description of the SDN file in the Windows registry
• Defective install of a SDN program, such as ARJ Software JAR
• The SDN itself is corrupted
• Malware-tainted SDN file can't be opened
• Drivers associated with SDN software need to be updated
• Too many applications are open on your PC to load your Shareware Distributors Network File file successfully
