If installation on the client computer fails, make sure that:
The files exist in the location specified on the server.
The link on the publish page matches the location where the files have been published.
The user has access rights to the publish server.
There is sufficient space on the user’s computer.
The network connection to the publish server is working correctly.
You have not used localhost as the publish or install location.
If the publish page fails to open on the client, check the firewall settings on the publish server. The firewall must be turned off on the server.
If the setup.exe file is not downloaded when a prerequisite is selected, open the Properties dialog box for the HTTP directory in IIS Manager and make sure the script source access permission is enabled. If the Execute Permissions property is not set to Scripts only, select Scripts only from the drop-down list and refresh the server.
