Dear Microsoft team,
I have trouble to run our application written in VB Excel using our proprietary DLL which is properly referenced in that VB Excel. The problem is that when I run this application in Excel, error message appears "Class is not Registered". It appears at the line Set io_line = New clsIOLine. I can see that the required library (class clsIOLine) is referenced in that VB Excel (in Tools->References). I can say that this application is working well in Office 2016. Would you know how I can get rid of this error?
Thank you
Best Regards
Jiri
