Register SELOGCOM in COM Plus

Register SELOGCOM in COM+

The steps here are only required on a SECI instrument that needs an updated ISISICP, or an IBEX instrument that may revert back to SECI at some stage

Open GENIE is a 32bit program, the ISISICP is 64 bit, and a DCOM component called SELOGCOM is used by SECI and Open GENIE to log values. This component is no longer built in 32bit format, SECI already uses the 64bit version (built as part of isisicp) but a workaround is needed for Open GENIE.

Many DCOM components are run in-process and need to be of the correct architecture, however if a DLL component is registered with COM+ it will automatically be run out of process using dllhost.exe and so be callable by any architecture.

Registering SELOGCOM with COM+

• create a CMD windows with admin privileges
• type dcomcnfg
• select component service -> computers -> my computer
• open COMP+ Applications and confirm SELOGCOM is not already there
• right click on com+ applications, select new application and create empty application
• when prompted, chose server application, name it SELOGCOM and accept the remaining default answers.
• right click on selogcom in COM+ applications, in properties, security tab uncheck/disable "enforce access checks for this application"
• open up the selogcom tree in explorer, right click on components and select new component then install new component, browse to C:\labview modules\DAE\service\x64\Release\selogcom.tlb
