SIG File Complications


Troubles Opening SIG Files

Microsoft Outlook Express Disappeared

You attempt to load your SIG file and get an error such as "%%os%% Can't Open The SIG File Extension". If this is the case, it's usually due to the fact that you do not have Microsoft Outlook Express for %%os%% installed on your computer. You won't be able to double-click to open your SIG because your OS doesn't know what to do with it.


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


Obsolete Version of Microsoft Outlook Express

Occasionally, you might have an outdated version of Microsoft Outlook Express installed that's incompatible with your Signature File type. Installing the latest version of Microsoft Outlook Express from Microsoft Corporation is recommended. 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: You can sometimes get hints about the right program version by right-clicking on the SIG file, selecting "Properties", and looking at the version information.


Conclusion: The majority of SIG file opening issues are due to not having the correct Microsoft Outlook Express version installed.


More Causes of Problems Opening SIGs

In the majority of cases, installing the right version of Microsoft Outlook Express will resolve your issue. If you are continuing to have errors with loading SIG files, other external issues might be to blame. Problems unrelated to software:

  • File references in the Windows Registry for SIG are wrong
  • Corruption of the SIG file description inside the Registry
  • Partial installation of Microsoft Outlook Express that did not fully complete
  • Something has caused file corruption of your SIG
  • Malware-tainted SIG file can't be opened
  • Hardware related to SIGs has device driver corruption
  • Your computer does not have the adequate system resources to open the Signature File format
