Description

I build a RubyTest.dll by C#, In ruby2.2, I could use WIN32OLE.new to create ole object, but in the same system under ruby2.6.3, it failed to create ole object by WIN32OLE.new, is there any different between ruby 2.2 and ruby 2.6.3 in WIN32OLE?

OS: Win7 Profressional SP1 64bit

It's hard to debug issues like this without having a self contained reproducible example. Can you provide a self contained reproducible example showing the problem? Basic testing of WIN32OLE using Ruby 2.6 on Windows 10 with the examples in the documentation (which use Excel.Application) work fine, so this doesn't appear to be a general problem with WIN32OLE.
