In order to run 32 bit web applications on a 64 bit Windows operating system (e.g. Vista x64, Windows Server 2008 x64), IIS has to be configured to allow this (by default, this is not enabled).

DataFlex 19.0 and higher support running DataFlex WebApp Server in 64-bit mode. These changes remove the need to install the IIS 6 Metabase Compatibility or enable 32-bit support in the Application Pool (assuming that you are able to solely use 64-bit).


Windows 7, Windows 8 and Windows 10:
1. Open the IIS Manager via Control Panel > Administrative Tools > Internet Information Services (IIS) Manager
2. In the Connections panel on the left, select Application Pools
3. Right click on DefaultAppPool on the right (Assuming your Web Applications use the DefaultAppPool and not another application pool)
4. Click on Advanced Settings in the context menu
5. Under (General) settings - set Enable-32 Bit Applications to True

The above steps assume that you have already installed the IIS Management Console. If not, you can do so using these steps:
1. Control Panel > Programs and Features
2. Click on 'Turn Windows Features on or off' on the left
3. Expand Internet Information Services
4. Expand Web Management Tools
5. Check 'IIS Management Console'


Windows Server 2008:
1. Open Server Manager
2. Expand Roles | Web Server | Internet Information Services (IIS)
Manager
3. On the tree on the right, click on Application Pools
4. On the panel to the right, select DefaultAppPool
5. From the Action panel, select Set Application Pool Defaults
6. In the General group, highlight Enabled 32-bit Applications
7. From the combo, select True
8. Click on OK

Windows Server 2012:
1. On the taskbar, click Server Manager,
2. Click Tools
3. Then click Internet Information Services (IIS) Manager
4. In the Connections pane, expand the server name, and then click Application Pools.
5. In the Actions pane, click Set Application Pool Defaults...
6. In the General group, highlight Enabled 32-bit Applications
7. From the combo, select True
8. Click on OK

OTHER STEPS:
- On Windows Vista and Windows 7, you may also have to enable ASP. KBase article 2273 shows you how to do so.
