An addendum:
In response to your comment about copying correctly:
I downloaded the LS2 zip file to my local Win7 Machine, and copied/unzipped the internal files [ie, the ones inside the zipped LS folder] to my local machine. With the files placed in a local directory "limesurvey2", I then uploaded the entire pile to a directory on the Linus/Apache 1.3.3 server by the same name, using a binary FTP.
I pointed to the install URL as:
www.mydomain.com/limesurvey2/index.php/installer
and received the returned error page, with this sole content:
"No Input File Specified"
While I received that error attempting an install, I was able to execute a phpinfo.php stored in the root directory of my machine, and could run ZenCart and its PHP [from which I conclude there is something specific to the LS install, and the way my ISP interacts with it...? This behavior, I allude to above, is reported on installs with prior versions, and on this ver 2. One cure, to amend the $rooturl variable in a config.php at the LS root, is not available to me, as the LS install bureaucracy has changed.
