Asalam Alaikum (Greetings!)
I am using Windows 7 x64, and install Oracle Workflow Builder by using Patch 6970344. But when I try to install, it shows an error on regsvr, and I skip by press ignore. But after installation, when I open Oracle Workflow Builder, it shows error

I read nearby all documents available on the internet, which helps to fix these types of errors or workflow builder errors, but that was not helpful.
Kindly help regarding the issue.
Regards
