Topic: message error when I open simpleviewer

I tried to install Simpleviewer on my server which works with pixelpost  into a  HTML page like explained in the FAQ, but after on my website when I open simpleviewer, I have this message:

Multiple Choices
The document name you requested (/index.html) could not be found on this server. However, we found documents with names similar to the one you requested.
Available documents:

/index.php?detectflash=false (common basename)
Please consider informing the owner of the referring page about the broken link.

If anyone can help me?

Thank you
