Hi Rufnex

Lightstreamer cannot be installed on Apache as a plugin.
It can only be used beside Apache, as a second server.
The latter usage scenario is described in README.TXT, under
DOCS-SDKs\sdk_client_web\examples\StockListDemo
where the "External deployment" section shows how you can deploy the demo pages in a web server and have them get real time data from Lightstreamer Server.

All the shell scripts included in the tar package have the execution permission flags set.
Perhaps something went wrong in the tar expansion.
Did you expand the zip package and then copy the files into unix/linux? This would explain all.
Please, recover by setting the 755 permission flags to all script files included.
