This is the entry I made for the LOV maximum records. This helped display all of the records in my RUntime version of Crystal which was installed by an accounting system. If I go into Crystal Reports Designer, I do not see all of the LOVs just 1000.
HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Crystal Reports\DatabaseOptions\LOV
For my batch size this is what I have done
HKEY_CURRENT_USER\Software\SAP BusinessObjects\Suite XI 4.0\Crystal Reports\ReportView
and changed PromptingLOVBatch Size - 2000 Unfortunately the batch size does not change for my runtime or crystal reports designer
