I am encountering numerous instances of identical error codes while working with Autodesk installations and removals. To illustrate:
I am wondering if either of the approaches for using parallel and redundant exit codes is considered newer, or if Microsoft has always utilized them. Additionally, I would like to know if there is a recommended approach between the two. As I am starting to create my own installers, I want to ensure that I am following the correct sequence, if there is one. If there is no established best practice, I believe using positive numbers would result in shorter logs.
Duplicate Error Codes in Autodesk Installs and Uninstalls
When working with Autodesk installations and removals, you may encounter numerous instances of identical error codes. This can be confusing, especially when trying to troubleshoot and resolve issues. In this post, we will take a closer look at two specific error codes that are commonly duplicated: 3010 and 1618. We will also explore the use of parallel and redundant exit codes and whether there is a recommended approach between the two.
Understanding Error Codes
Before we delve into the specific error codes, let’s first take a moment to understand what error codes are and how they work. An error code is a unique identifier that is assigned to a specific error or issue that occurs during an installation or removal process. These codes are used to help diagnose and troubleshoot issues and can provide valuable information on what went wrong and how to fix it.
When an error occurs during an installation or removal process, the installer will typically display an error message that includes an error code. This code can then be used to look up more information on the specific error and how to resolve it. Error codes are also logged in installation logs, which can be useful for diagnosing issues after the fact.
Error Code 3010
Error code 3010, also known as ERROR_SUCCESS_REBOOT_REQUIRED, is a common error code that is often encountered during software installations. This error code indicates that a reboot is required to complete the installation process. This can occur when certain components or files are in use and cannot be updated or replaced until the system has been restarted.
It is worth noting that error code 3010 is not necessarily an error in the traditional sense. Rather, it is a notification that a reboot is required to complete the installation process. As such, this error code is often accompanied by a message that instructs the user to reboot their system before continuing with the installation.
Duplicate Error Code 3010
As mentioned earlier, it is not uncommon to encounter duplicate error codes when working with Autodesk installations and removals. In the case of error code 3010, you may encounter two different codes that both indicate that a reboot is required:
So, why are there two different error codes that indicate the same thing? The answer lies in the use of parallel and redundant exit codes.
Parallel and Redundant Exit Codes
Parallel and redundant exit codes are two approaches that Microsoft uses to handle error codes during installations and removals. Parallel exit codes involve using both positive and negative exit codes to indicate success or failure. Redundant exit codes involve using multiple exit codes to indicate the same thing.
In the case of error code 3010, we can see that both parallel and redundant exit codes are being used. The positive exit code (3010) indicates success, while the negative exit code (-2147021886) indicates failure. This redundant approach ensures that the error code is captured regardless of whether the system is using positive or negative exit codes.
So, is there a recommended approach between parallel and redundant exit codes? The answer is not necessarily straightforward. Both approaches have their pros and cons, and the best approach may depend on the specific installation or removal process.
That said, some experts recommend using positive exit codes whenever possible. This is because positive exit codes are easier to read and understand, and they can result in shorter logs. However, there may be cases where using negative exit codes is necessary, such as when working with legacy systems or specific software that requires it.
Ultimately, the approach you choose will depend on your specific needs and requirements. It is important to understand both parallel and redundant exit codes and to use them appropriately to ensure that error codes are captured and logged correctly.
Duplicate error codes can be confusing and frustrating, but understanding how they work can help you diagnose and troubleshoot issues more effectively. By understanding the use of parallel and redundant exit codes, you can ensure that error codes are captured and logged correctly, and that you are following best practices when creating your own installers. Whether you choose to use positive or negative exit codes, the most important thing is to be consistent and to use them appropriately.
It’s common for software to use both positive and negative versions of error codes, and this is not specific to Autodesk or Microsoft. In general, error codes are just integers that are used to indicate the outcome of an operation. The positive and negative versions of a particular error code usually mean the same thing and can be used interchangeably.
As for which version to use in your own installers, it really doesn’t matter which one you choose as long as you are consistent. Some developers might prefer to use the positive version because it takes up less space in log files, while others might prefer the negative version because it’s easier to remember the difference between positive and negative numbers. Ultimately, the choice is up to you and what works best for your needs.
When it comes to Windows user mode, error codes are primarily utilized in two ways: HRESULT and Win32 error codes. HRESULT is commonly used in COM programming and represented as a hexadecimal value. After a successful operation, methods will return S_OK (0), and negative values (starting with 0x8) indicate failure. On the other hand, Win32 error codes are integers ranging from 0 to 65535 (
2^16 - 1). With the help of specific macros outlined in the WinError.h header file in Windows SDK, it is possible to convert both forms of error codes into one another. The following examples demonstrate this process:
#define FACILITY_WIN32 7 #define __HRESULT_FROM_WIN32(x) \ ((HRESULT)(x) <= 0 ? ((HRESULT)(x)) : ((HRESULT) (((x) & 0x0000FFFF) | (FACILITY_WIN32 << 16) | 0x80000000))) #define HRESULT_CODE(hr) ((hr) & 0xFFFF)
The conversion process for the example mentioned above would be as follows:
-2147021886 = 0x80070BC2 = (0x80070BC2 & 0xFFFF) = 0xBC2 = 3010 -2147023278 = 0x80070625 = (0x80070625 & 0xFFFF) = 0x652 = 1618
The error codes, whether they are HRESULT or Win32 error codes, are specified in the WinError.h header file. When working with COM programming, it is recommended to use HRESULT, as installers frequently utilize COM. If utilizing Win32 APIs, it is preferable to use Win32 error codes, which are returned by GetLastError. To obtain the equivalent error message, similar to strerror() in the Linux world, both types of error code formats can be passed to FormatMessage().
