Are you following David Powers' tutorial?

He explains it here

Enabling connection to an Access database on 64-bit Windows

http://www.adobe.com/devnet/dreamweaver/articles/setup_asp.html#articl econtentAdobe_numberedheader_1

Any reason you're using Dreamweaver for ASP (or are you using ASP.NET?) development?

Since it's a Microsoft proprietary technology, Adobe lost interest in ASP back around CS4. They left the tools there but don't develop or support them anymore.

ASP developers are better off using Microsoft Expression Web.

Does the current tutorial you're following work for you?

I have Windows 7 Ultimate here and I just followed the tutorial. Works OK.

Which flavour of Windows 7 are you running?

Can you get to the IIS Manager?

• Launch the Internet Information Services Manager by selecting Start > Control Panel > Administrative Tools > Internet Information Services (IIS) Manager.

From the tutorial

Enabling connection to an Access database on 64-bit Windows

The Microsoft Access Driver is not available in a 64-bit version, so you need to use the 32-bit driver.

1. Launch the Internet Information Services Manager by selecting Start > Control Panel > Administrative Tools > Internet Information Services (IIS) Manager. 
2. In the Connections panel, select Application Pools, and select DefaultAppPool in the center panel. 
3. In the Actions panel on the right, click the Advanced Settings link. 
4. In the General section, set Enable 32-Bit Applications to True (see Figure 13), and click OK.

I'm guessing that you're running Windows 7 Home Premium?

IIS is not installed by default on the Home versions of Windows 7.

Do you have to use ASP (which needs IIS)?

PHP, free and open source, is a much more popular choice for web developers these days and does not rely on IIS at all.
