Wondering how to fix error code 30045-29 on Microsoft Office on Windows?

Most OEMs include a trial version of MS Office with their laptops/systems. Most users either subscribe to these applications or uninstall them after a while. If you do not subscribe, the Office services usually prompt you to do so. 

Recently, several users reported that their screens display error code 30045-29 at odd times. We had a look into this issue, and discovered that it could be caused by mainly two reasons which are as follows:

  • Your trial period has expired and Office failed to update itself
