This is probably a question best answered by the support at Wix.
Installation of any SSL on their servers/system is specific to their installation. The information provided by the issuing authority (GoDaddy) is standard information. How this information is integrated into a server is dependent upon the hosting company's installation routine. This varies from hosting company to hosting company.
question was not asking how to install it on WIX, but in order to download the proper zip file from GoDaddy you need to answer the server type question first. I contacted WIX but haven't received a response I just need to know if it is Apache, Tomcat, IIS, or other so I cn download my new SSL files. thx.
