You are correct - as long as you configured the install to use clickonce. To see more on how to use clickonce, search the help file for clickonce:
SAP Crystal Reports .NET SDK Developer Guide
Note that you can use the MSM to create your own deployment project in VS, or using InstallSHield, etc.
You can also use the MSI = just a simple double click on the file will start the install.
