How to load an Add-in, both now and at SW startup

I'm writing a macro that loads add-ins for toolbox and PDM Workgroup. I'm using the LoadAddIn function (and UnloadAddIn). When loading the addin for PDMWorkgroup it sets both current status to load and load at startup. However the toolbox addins (there are 2) only changes the current status. I'm using the same function, but getting different results.

Any ideas why? and how do I work around it?

Thanks,
