inroads Add-ins

When initializing the Application Add-Ins through Tools > Application Add-Ins, the program will hang and eventually crash.  This is only affecting the SS2 product at this time as we tested in SS4 and the command will initialize without an issue. Possible solution is to re-install Pre-Req pack  pdba08110706en.exe.. is there a link to this. I am unable to find download on the Bentley site
