Troubleshooting Problems Opening CONTACT Files

Troubles Opening CONTACT Files

Missing Microsoft Windows

When you double-click your CONTACT file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Generally, this is experienced in %%os%% because Microsoft Windows isn't installed on your PC. You won't be able to double-click to open your CONTACT because your OS doesn't know what to do with it.

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

Microsoft Windows Requires Update

Sometimes your installed version of Microsoft Windows won't support your Windows Contact File file. If you do not have the proper version Microsoft Windows (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. The primary cause of this problem is that your Windows Contact File file was created by a different (newer) version of Microsoft Windows than what's installed.

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

Conclusion: The majority of CONTACT file opening issues are due to not having the correct Microsoft Windows version installed.
