How to remove Windows updates:
Once this has been uninstalled from your machine you will need to restart Windows.
This should resolve the issue and allow you to export / print to PDF successfully.
In order to prevent this update from being re-installed you can remove an item from the list without installing it, you hide it.
Tthe option for hiding updates in the list is itself somewhat hidden and often goes overlooked.
In the list of available updates, right-click any update that you don’t want to see again (KB3102429), and choose Hide Update.
If you later change your mind—or if you just want to see a list of the updates you’ve chosen to hide—on the main Windows Update page, click Restore Hidden Updates.
Please note: This is temporary solution to this problem and we will be looking to release a permanent fix to this in a future update of the Keytime software.
