Instantiating Openstaad Issuue

Dear Everyone,

I have done some coding using Excel OPENSTAAD. I used :

Dim objOpenSTAAD as object

Set objOpenSTAAD = GetObject("StaadPro.OpenSTAAD").

Usually when i execute the command, STAAD opens up by itself runs the analysis.

But all of sudden im getting run time 429 error (ActiveX can't creat this components). The analysis runs only after i have opened the STAAD. There is some way to bypass this to enable excel to open STAAD automatically. 

The system I use was WIN10.

Thank You
