In one of the articles, (https://community.nintex.com/docs/DOC-1007) it was mentioned that the Nintex exe can be run on WFE in a multi server farm hosting the Central Administration (CA). In our farm CA is hosted on one of the app servers. So in our farm, would it be ok running the exe on app server hosting the CA. Or should it be run on one of the WFE servers? Does it matter on which server the exe is run on? what is the correct way to update Nintex in a multi server farm. Thanks in advance.
