RAPID PUBLISHING ARTICLES PROVIDE INFORMATION DIRECTLY FROM WITHIN THE MICROSOFT SUPPORT ORGANIZATION. THE INFORMATION CONTAINED HEREIN IS CREATED IN RESPONSE TO EMERGING OR UNIQUE TOPICS, OR IS INTENDED SUPPLEMENT OTHER KNOWLEDGE BASE INFORMATION.
You are using Visual Studio 2005Â or Visual Studio 2008Â to develope an application that implements Visual SourceSafe automation.
You find that the code compiles on a 32-bit
Windows
operating system but fails on a 64-bit Windows operating system with the error:
Retrieving the COM class factory for component with CLSID {783CD4E4-9D54-11CF-B8EE-00608CC9A71F}
failed due to the following error:Â 80040154
The code in Visual Studio was compiled in 64-bit by default. Visual SourceSafe is a 32-bit application; therefore, you get an error.
Alter the build parameters of Visual Studio to build the code in 32-bit. To make this change, do the following:
- Choose Build from the menu then click Configuration Manager.
- Change Active Solution Platform to <New>.Â
- Change "Type or Select the new platform" to x86 in the New Solution Platform dialog.
- Recompile the code project.
Compiling a simple VS 2005 Visual Basic .Net console application with this code demonstrates the problem:
Module Module1
Sub Main()
Dim vssDatabase As New VSSDatabase
Dim vssProject As IVSSItem
End Sub
End Module
