Can't register StyleGallery.dll when install my program (using Visual Stdudio,C#)

Hi everyone,

In my program, I used the IStyleGallery (need using ESRI.ArcGIS.Framework).

When I install and run my program. I got the error: "Retrieving the COM class factory....".

And, I discovered the reason is the file: StyleGallery.dll isn't registered and not exist in the folder: C:\Program Files\ArcGIS\bin.

So, I used "regsvr32" to register this dll file. And successful without error

Are there anyone know how to fix this problem ?

Thanks and regards,

Tai
