Installing DeLeach:

Download and install the latest version:

You can download Deleach from here. You can save the file to your local disk, and execute it from there, or you can execute it from your browser.

You should perform the installation on the machine which runs your IIS webserver, and you will need to be logged-on as an administrator.

The installer program is conventional, and perfectly simple. During the installation, the webserver will be shut down for a second or so to permit files to be synchronised.

Checking your installation

DeLeach performs all the setting-up for IIS, so you shouldn't have any problems. To check that DeLeach has installed correctly:

In the IIS manager, right-click on websites,
click Properties,
click ISAPI filters,
make sure DeLeach appears in the list of installed filters, and that it has a green arrow beside it.
In case of difficulty, you may need to install DeLeach manually.

If you're running IIS 6.x, and you're using the Free version, then you will have to switch IIS into IIS 5.0 Isolation Mode.

In the IIS manager, right-click on the websites,
click Properties,
click Service,
make sure Run WWW service in IIS 5.0 isolation mode is checked.
In case of difficulty, you may need to install DeLeach manually.

More advanced installations:

By default, DeLeach installs itself into the main server ISAPI filter set. That will usually be suitable for most purposes: if it's not being used on a website, it creates no additional server overhead.

It is possible, if you prefer, to install it into a selection of websites on your server. In that case, you will have to perform sompe parts of the installation manually.

Remove DeLeach from the main server ISAPI set.
- In the IIS manager, right-click on websites,
- click Properties,
- click ISAPI filters,
- Cick on DeLeach and then click Remove.
Do not use the uninstaller - that will delete all the DeLeach files from your computer.
Install DeLeach into each of the websites you want:
- In the IIS manager, click on websites to open the list of websites, and right-click on the website you want to install DeLeach into,
- click Properties,
- click ISAPI filters,
- Cick on Add and fill in the dialog:
  - Filter Name should be "DeLeach"
  - Click Browse, navigate to C:\Program Files\Webgineers\DeLeach (or whatever other installation directory you selected), and select Deleach.dll
  - Click OK
Repeat for each website you want to install DeLeach onto.
Restart your computer.
