AddIn - Failed to register the COM DLL on Save-As dialog from 32bit Programs

Hello,

 

i have written an AddIn (with vb.NET) and have successfully added it to our EPDM.

I have used the example: 2017 SOLIDWORKS API Help - Creating Add-ins (VB.NET)

 

Everything looks good. If i use the Windows-Explorer the AddIn is working.

 

But if i enter the Save-As Dialog from e.g. Word/Notepad++/... i get the error message:

Failed to register the COM DLL

 

It seems that this only happens if the Dialog is opened from a 32bit process.

 

What can i do to avoid these error? This happens on all clients. (Win7 and Win10)

 

We use:

PDM Professional 2018 (18.4 (B76))

SolidWorks 2017 SP5

Visual Studio Community 2015

 

Regards

Sascha
