Registering a COM DLL in MSI Using Wix Msi Installer
Why Batch Files and Custom Actions Should be Avoided
Batch file and custom action methods for COM registration are unreliable. To ensure successful registration, it's essential to use the heat.exe tool from the WiX toolkit. This tool extracts COM registration information for inclusion in the MSI database during compilation.
Extracting COM Registration Information Using heat.exe
Run heat.exe on the COM file (for example, "heat.exe file Abc.dll -o Abc.wxs") to generate the corresponding WiX XML with the required registry data. Incorporate this XML into your main WiX source using a reference or embedding technique.
Ensuring Dependency Resolution
Missing dependencies can prevent COM registration. Use Dependency Walker or Dependencies.exe to identify missing DLLs. Place these DLLs alongside the COM file or ensure they are accessible in the installation path.
Considerations for 64-bit Binaries
Currently, heat.exe has limitations in handling 64-bit COM binaries. The WiX Expansion Pack offers support for 64-bit components if necessary. Alternatively, you may consider self-registration as a temporary solution, but it's not recommended as it can introduce challenges during installation.
Additional Tips
- Always run COM registration from an elevated command prompt.
- Heat.exe does not extract any custom .NET assemblies (such as RegAsm.exe generates) for COM registration.
- The SourceDir path generated by heat.exe may contain placeholder paths. Adjust them as needed to accurately reflect the installation directory.

C XML Libraries: Comparing and Contrasting OptionsApr 22, 2025 am 12:05 AMThere are four commonly used XML libraries in C: TinyXML-2, PugiXML, Xerces-C, and RapidXML. 1.TinyXML-2 is suitable for environments with limited resources, lightweight but limited functions. 2. PugiXML is fast and supports XPath query, suitable for complex XML structures. 3.Xerces-C is powerful, supports DOM and SAX resolution, and is suitable for complex processing. 4. RapidXML focuses on performance and parses extremely fast, but does not support XPath queries.
C and XML: Exploring the Relationship and SupportApr 21, 2025 am 12:02 AMC interacts with XML through third-party libraries (such as TinyXML, Pugixml, Xerces-C). 1) Use the library to parse XML files and convert them into C-processable data structures. 2) When generating XML, convert the C data structure to XML format. 3) In practical applications, XML is often used for configuration files and data exchange to improve development efficiency.
C# vs. C : Understanding the Key Differences and SimilaritiesApr 20, 2025 am 12:03 AMThe main differences between C# and C are syntax, performance and application scenarios. 1) The C# syntax is more concise, supports garbage collection, and is suitable for .NET framework development. 2) C has higher performance and requires manual memory management, which is often used in system programming and game development.
C# vs. C : History, Evolution, and Future ProspectsApr 19, 2025 am 12:07 AMThe history and evolution of C# and C are unique, and the future prospects are also different. 1.C was invented by BjarneStroustrup in 1983 to introduce object-oriented programming into the C language. Its evolution process includes multiple standardizations, such as C 11 introducing auto keywords and lambda expressions, C 20 introducing concepts and coroutines, and will focus on performance and system-level programming in the future. 2.C# was released by Microsoft in 2000. Combining the advantages of C and Java, its evolution focuses on simplicity and productivity. For example, C#2.0 introduced generics and C#5.0 introduced asynchronous programming, which will focus on developers' productivity and cloud computing in the future.
C# vs. C : Learning Curves and Developer ExperienceApr 18, 2025 am 12:13 AMThere are significant differences in the learning curves of C# and C and developer experience. 1) The learning curve of C# is relatively flat and is suitable for rapid development and enterprise-level applications. 2) The learning curve of C is steep and is suitable for high-performance and low-level control scenarios.
C# vs. C : Object-Oriented Programming and FeaturesApr 17, 2025 am 12:02 AMThere are significant differences in how C# and C implement and features in object-oriented programming (OOP). 1) The class definition and syntax of C# are more concise and support advanced features such as LINQ. 2) C provides finer granular control, suitable for system programming and high performance needs. Both have their own advantages, and the choice should be based on the specific application scenario.
From XML to C : Data Transformation and ManipulationApr 16, 2025 am 12:08 AMConverting from XML to C and performing data operations can be achieved through the following steps: 1) parsing XML files using tinyxml2 library, 2) mapping data into C's data structure, 3) using C standard library such as std::vector for data operations. Through these steps, data converted from XML can be processed and manipulated efficiently.
C# vs. C : Memory Management and Garbage CollectionApr 15, 2025 am 12:16 AMC# uses automatic garbage collection mechanism, while C uses manual memory management. 1. C#'s garbage collector automatically manages memory to reduce the risk of memory leakage, but may lead to performance degradation. 2.C provides flexible memory control, suitable for applications that require fine management, but should be handled with caution to avoid memory leakage.
