Misc Problems and Solutions

I’ve installed everything properly but don't see any suggestions

Your profile hasn’t been created yet: if you have multiple languages installed on your computer and you selected a large number of categories Lightkey may need a few more minutes to complete the creation of your profile. In which case you will see a progress bar indicating that Lightkey is still working on creating your profile. Predictions will only start to appear after the profile creation process is complete.

Your language isn't supported: Lightkey should have prompted you with a compatibility message before the download process started, but just in case you may want to enter your profile to ensure your installed languages are supported by Lightkey. Simply go to Lightkey's Control Center and click on the “Prediction Profile” tab to review your installed languages.

You are typing content that matches a different input language: In some cases, you may use your current input language (for example, Danish) to type content in a different target language (for example, English). The solution is to add your target language (English) to the list of Input Languages in Windows Region & language settings and then activate this language in Lightkey's control center - open Lightkey's Control Center and click on the “Personal Profile” tab and ensure that your target language is selected.

Your Office version isn't supported: Lightkey supports MS Office versions 2010, 2013, 2016 and 365. If you have an older version of Office Lightkey will not offer any predictions. However, you will still be able to use ‘LightkeyPad’ which provides basic text editing features along with Lightkey's text prediction capabilities.

For any other issues you are welcome to download and review our Technical Support Guide.

In case you are working in a multi-display environment, please follow our multi-display scaling guide.
