This looks wrong. I have this in my ini file:

WebFolder = C:\inetpub\wwwroot\zorro

Make sure that the folder exists. It probably also works with double quotes, but most likely not with double backslashes. The "\\" is used for string constants in C source code, not for file names in an ini file.

Also when changing the .ini file make sure to restart Zorro - the .ini file is only read once at the begin.
