• During install of Sage 300 ERP the Crystal Runtime Engine install may not have completed properly.
• To check if the engine has installed properly please view the contents of the following directory:
• *For 32bit Windows - "C:\Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86"
• *For 64bit Windows - "C:\Program Files(x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86".
• A completed install should have more than 265 files located in that directory. In some cases the directory had only 8 to 15 files listed.
  

Check that Microsoft .Net is installed, and all applicable Windows Updates are successfully competed.

Rerun the Sage 300 ERP installation.
