If you have installed ARIS locally together with the local standard database system, you need the 32-bit version of SAP® JCo 3.0.x (sapjco3.jar/sapjco3.dll) from version SAP® JCo 3.0.9, that you have made available to the locally installed client. For the local standard database system, you also need the 64-bit version. For licensing reasons, the unsigned files must not be automatically copied during installation.
Procedure
SAP JCo 3.0.x is available after you restart ARIS.
If you supplied SAP® Java Connector SAP JCo 3.0.9 properly, but installed older runtime library versions than Visual Studio 2005 C/C++, you may have to update the Microsoft® Active Template Library (ATL) (download Microsoft® ATL patch; http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=766a6af7-ec73-40ff-b072-9112bab119c2). Please read SAP® notes 1077727 and 1375494 in SAP Service Marketplace.
