If including a merge module that meets the following criteria, some additional steps must be taken to ensure a successful installation:

• Created with Microsoft Visual Studio .NET 2003 or 2005 or 2008
• Contains an assembly that has an Installer Class

By default, when a merge module that meets the above criteria is inserted into a project, error -1001 occurs at run time. An example of this error is as follows:

Error 1001.InstallUtilLib.dll: Unknown error in CorBindToRuntimeHost (0x80131700).

This error occurs because some additional steps must be taken to configure the project to support this type of Merge Module. Follow these steps to ensure a successful installation:

1. Select the Direct Editor view.
2. Select the InstallShield table in the center column.
3. Create a new row in this table.
4. In the Property column, enter the value: _ISSupportedRuntimes.
5. In the Value column, enter a semicolon-delimited list of versions. Example: 1.1.4322;1.0.3705 or 2.0.50727 or 4.0.30319
6. In Windows Explorer, create a blank file named "_isconfig.xml". See attached _isconfig.xml file for an example.
7. Select the Support Files/Billboards view.
8. Insert this "_isconfig.xml" file in the Language Independent section of this view.
9. Select the Custom Actions view.
10. Create a new custom action with the following settings:

    Type: Set a property

    Source: VSDFxConfigFile

    Target: [SUPPORTDIR]\_isconfig.xml

11. Insert this custom action as the first action in the Installation | Execute sequence via the Sequences view.
12. Rebuild the project.

The file and property specified in Step 7 are created by default during the build process when the property specified in Step 4 is created in the InstallShield table. The values listed in Step 7 will not be available in the drop-down box, but must be manually entered.
