3IN Troubleshooting

Common Problems Opening 3IN Files

MSN Explorer Isn't There

When you double-click your 3IN file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Usually, this is because you do not have MSN Explorer for %%os%% installed. This will prevent you from double-clicking to open the 3IN file because the OS doesn’t know how to handle it.

Tip: When another 3IN application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Incorrect MSN Explorer Version

In other instances, your MSN Setup Information file version may not be supported by your version of MSN Explorer. You will need to download a newer version of MSN Explorer if you don't have the right version. This issue mainly occurs when your MSN Setup Information file was created by a newer version of MSN Explorer than you have on your PC.

Tip: If you right-click on your 3IN file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Ultimately, most of the difficulties opening 3IN files are due to having the wrong version of MSN Explorer installed.

Other Causes of 3IN File Opening Problems

You can still experience errors opening 3IN files even with the latest version of MSN Explorer installed on your PC. If you are continuing to have errors with loading 3IN files, other external issues might be to blame. Additional factors include:

• Windows Registry 3IN file paths that are incorrect
• Deletion of the 3IN file description from the Registry by mistake
• Partial installation of MSN Explorer that did not fully complete
• The 3IN itself is corrupted
• Malware-tainted 3IN file can't be opened
• 3IN-related hardware has device drivers that obsolete
• Your computer does not have the adequate system resources to open the MSN Setup Information format
