Unhandled Exception After Installing Coveo for Sitecore on Sitecore 8.0 or 8.1 Instance
Sitecore 8.0.0 - 8.0.5, 8.1.0
Symptoms
After installing Coveo for Sitecore on a Sitecore 8.0 or 8.1 instance, Sitecore crashes with the following error message:
Unhandled exception error message:
Exception: Sitecore.Exceptions.ConfigurationException
Message: Could not create instance of type: Sitecore.ContentSearch.FieldReaders.FieldReaderMap. No matching constructor was found.

at Coveo.SearchProvider.Events.CachedFieldsEventHandler…ctor()Cause
Coveo added a line to the Coveo.SearchProvider.config file to improve the cache, so it wouldn’t create multiple instances of the same FieldReaderMap cache each time the indexes were called:
<param desc="id">coveoFieldReaderMap</param>However, this line leverages the id param of the Sitecore <fieldReaders type="Sitecore.ContentSearch.FieldReaders.FieldReaderMap, Sitecore.ContentSearch"> element.
The id param didn’t exist in early releases of Sitecore 8.0 and 8.1.
Coveo provides one package for all Sitecore 8.0 releases (i.e., Sitecore 8.0 initial, Sitecore 8.0 update 1, etc.), and one for all Sitecore 8.1 releases.
The Coveo for Sitecore packages for Sitecore 8.0 and 8.1 versions contain a Coveo.SearchProvider.config file which assumes Sitecore supports this id param.
Resolution
Remove the <param desc="id">coveoFieldReaderMap</param> line from the Coveo.SearchProvider.config file.
