New to Daml

Hi,

I recently tried to run Canton on Windows 11 and below error . Is there any way to fix that or workaround ?
I have installed DAML SDK version 2.6.3 on my Windows 11 notebook.

Hi @el_daml01,

You are likely actually missing the actual Create Daml APP (create-daml-app) from your filepath.

I am using Ubuntu Linux, but I was able to get this example working correctly using the Linux version of your command:

bin/canton -c examples/04-create-daml-app/canton.conf --bootstrap examples/04-create-daml-app/init.canton

Process:

# Run the Canton Examples command

I tested this process on Canton Enterprise v2.6.2, v2.6.3 and Canton Open Source v2.6.3.

Hope this helps, Ben.
