At Sage Sessions Linda Cade mentioned an updated KB article would be forethcoming on various ways to fix error messages resulting from incompatible versions of Crystal Reports when using Sage Fixed Assets 2018.1 and any version of Sage 100 PRIOR to 2018.
[This appears to be that article](https://support.na.sage.com/selfservice/viewdocument.do?noCount=true&externalId=89164&sliceId=1&cmd=displayKC&dialogID=132697&docType=kc&isLoadPublishedVer=&stateId=132699&docTypeID=DT_Article&ViewedDocsListHelper=com.kanisa.apps.common.BaseViewedDocsListHelperImpl). Probably worth bookmarking.
