Consider the following scenario. You build a Microsoft .NET Framework 2.0-based application in Microsoft Visual Studio 2005. The application consumes licensed components on a computer that is running a 64-bit operating system. However, you compiled the application for a 32-bit operating system. In this scenario, the License Compiler (Lc.exe) throws an exception that resembles the following:
Exception occurred creating type
'LicensedComponent.UserControl1, LicensedComponent, Version=1.0.1.100,
Culture=neutral, PublicKeyToken=null' System.ComponentModel.LicenseException: A
valid license cannot be granted for the type LicensedComponent.UserControl1.
Contact the manufacturer of the component for more information. C:\Documents

64BitIssue

This problem occurs because the License Compiler always runs as a
64-bit application on a computer that is running a 64-bit operating system. However, the License Compiler does not support 32-bit applications that are running on 64-bit operating systems. the License Compiler only supports 32-bit applications that are running on 32-bit operating
systems.

To resolve this problem, build a binary file to specify that the application is built for a 32-bit operating system. Build the binary file by using the appropriate flags of the License Compiler.
Note Do not use the
Ldr64.exe command to force all code to run as a 32-bit application.
