Affected Programming Languages This error only affects you if you are using C# or VB.NET to build your application.   Chameleon Version 5.0 and Higher This issue is handled differently if you are upgrading to Chameleon version 5.0 and higher. For details, see PATH and Shared Assemblies.

Problem

After upgrading Chameleon to version 4.5, you may encounter the following error message when your application is running:

"Method not found: Error Message."

where "Error Message" represents the details of the specific error.

Symptoms

When your application is running, this error will occur when the Chameleon engine or networking components are used. More specifically, this error will occur if the Chameleon installer is unable to detect .NET on the machine during the installation process. The error message is as follows:

"No version of the Microsoft .NET Framework was detected. .NET objects will not be registered."

This will not prevent .NET applications from building or running. This means two things:

• The Chameleon C# module (CHM_SHARP.dll) will not be in the GAC, and
• If an old version of the Chameleon C# module is in the GAC, it will not be replaced by the latest version (this is the cause of the "Method not found" error message).

Solutions

Solution 1 is the recommended method since Chameleon no longer places the CHM_CSHARP.DLL file in the Global Assembly Cache (GAC).

Solution 1 (Recommended Method)

• Install the latest version of Chameleon.

• Right-click the CHM_CSHARP.DLL file in the $WINDIR\assembly\ directory, and select Uninstall. This removes the CHM_CSHARP.DLL file from the GAC.

• Place the latest CHM_CSHARP.DLL file (accessible from C:\Program Files\iNTERFACEWARE\Chameleon\csharp) in the same folder as your application.

• Run your application. When your application calls the engine or networking component methods, the error should no longer appear.

Solution 2

• Install the latest version of Chameleon.

• Right-click the CHM_CSHARP.DLL file in the $WINDIR\assembly\ directory, and select Uninstall. This removes the CHM_CSHARP.DLL file from the GAC.

• Install the CHM_CSHARP.DLL file from C:\Program Files\iNTERFACEWARE\Chameleon\csharp into the GAC.

• Run your application. When your application calls the engine or networking component methods, the error should no longer appear.
