Reliability Monitor: Webroot. Installation success or error status: 1603

My computers Reliability Monitor logs are flooded with the following error:

Windows Installer installed the product. Product Name: Core. Product Version: 1.1.227. Product Language: 1033. Manufacturer: Webroot. Installation success or error status: 1603

I can’t run a manual update either. 

I did see the other community entry about deleting the WRData folder but that has not helped. C: drive has plenty of space and I am not seeing any other issues.
