Troubleshooting Problems Opening UCCAPILOG Files

Frequent UCCAPILOG Opening Issues

Microsoft Windows Live Messenger Disappeared

You attempt to load your UCCAPILOG file and get an error such as "%%os%% Can't Open The UCCAPILOG File Extension". Customarily, this means that Microsoft Windows Live Messenger is not installed on %%os%%. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: If you don't have Microsoft Windows Live Messenger installed, and you know of another program to open your UCCAPILOG file, you can try opening it by selecting from the programs listed under "Show Apps".

Microsoft Windows Live Messenger is Out-of-Date

Your Microsoft UCC API Log File file is incompatible with Microsoft Windows Live Messenger because you might have the wrong version installed. You will need to download a newer version of Microsoft Windows Live Messenger if you don't have the right version. Most of the time your Microsoft UCC API Log File file was created by a newer Microsoft Windows Live Messenger than what you have installed.

Tip: You can sometimes get hints about the right program version by right-clicking on the UCCAPILOG file, selecting "Properties", and looking at the version information.

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