SAP Crystal Reports Install / Upgrade - server distribution

I'm new to SAP Crystal Reports.

Downloaded and installed SAP Crystal Reports Support Pack 16 both Install Executable and distribution files from MSI 64 bit.

All this was done in a local pc running IIS. Web application reports were created for and are working nicely.

Question: for distribution, do clients only need to run MSI 64 bit on their IIS server? Is there any guide for clients to install MSI or upgrade?
