There really is not much information about where the error message comes from.

Duncan, excellent work on the package. I am not able to get it on shinyapps.io though, however i suspect it is simply due to the fact that shinyapps.io is a Linux Ubuntu server. My simple app is:

library(shiny)
library(devtools)
library(RDCOMClient)

ui <- fluidPage(
   titlePanel("RDC"), sidebarLayout(sidebarPanel( ),mainPanel(plotOutput("distPlot"))))
server <- function(input, output) {}

shinyApp(ui = ui, server = server)

and the server response is:

Preparing to deploy application...DONE
Uploading bundle for application: 243075...DONE

Is it the Linux hiccup and nothing can be done or is it something particular about the way I installed it? I tried various ways, from cran, from 'omegahat' (no success with your server), from github and everything works fine locally on my windows machine, but fails on shinyapps.io

Any idea?

Hi RDCOMClient is really for Window. It requires the DCOM mechanism.

thank you, in other words it will not work whatever I try? Have you ever heard anything that would work with Linux shinyapps?

If you serve your shiny app on a Windows machine, then it can work. But the server has to be Windows. And you will need to install the other software to which you are connecting with DCOM.
