Licensee Acknowledgment

The information provided on this form is true and accurate to the best of my knowledge. I have read the license and warranty information and agree to its contents.

  • The Webinator binaries are available for the following platforms (hover over choices for more info):
  • Linux x86_64 64-bit: The Linux 2.6 x86_64 64-bit version is built with libc6 (aka glibc 2.3.4) on CentOS release 4.2. It requires an x86_64 kernel. It supports 64-bit files (>2 GB) and 64-bit memory, and runs on newer CentOS and RedHat versions, Fedora Core as well as other Linux distributions. It will not run on 32-bit x86 operating systems.
  • Linux x86 32-bit: The Linux 2.6 x86 32-bit version is built with libc6 (aka glibc 2.3) on CentOS 4.4 (RedHat EL 4 equivalent). It requires at least kernel 2.6.9 and libc 2.3.4. It supports 64 bit files (>2 GB). It runs on newer CentOS and RedHat versions, Fedora Core as well as other Linux distributions.
  • Windows Server 2008/2012 and later 64-bit:The Windows version will not work on Windows versions prior to Windows Server 2008 64-bit.
  • Other platforms may become available based on demand. Send us a request if you do not see yours, maybe we'll have it soon.
  • The free Webinator must have direct Internet access to on port 80 to run. (That may seem obvious, but some organizations have internal webs behind firewalls and proxies that block outbound port 80.) The Webinator checks with Thunderstone to validate its license.
  • We strongly urge you to be polite when indexing other people's Web servers. Like any web crawler, the Webinator can be abusive if mis-handled.
  • You must submit a registration form for each machine that will run the software. If you have purchased and installed a full Texis distribution, do not install this package onto the same machine. You may install it on a different machine. To use Webinator on an existing Texis installation, use the Webinator scripts that came with it (or contact tech support for updates) — they contain more functionality than the Free Webinator scripts.
  • This version of Webinator creates indexes that should not be accessed or modified by version 5 or earlier, if the data contains Unicode/international/hi-bit characters. Register and download the Free Webinator here
