Created Office Add-In doesn't work

Question

Hi there.

 

I am new at this Forum and i have a little Paoblem with a Add-In for Office.

I create an Add-In for Office with Visual Studio 2005. This Add-In should Add a new Symbol Border in Office. But the Problem is, that when i Install this Add-In on an other PC which did not contain Visual Studio, then Office did not load this Add-In.

I Use COM (MSCorEE.dll) to registry this Add-In.
What i am doing wrong? The Office Package is equal on the different Systems.

I did read a lot Articels in this Theme but there Solutions did not work.

thanks
