To find the human-readable text message for the error, you will need to prepend `0x00000` to the error number and then search the MSDN Win32 Error Codes for `0x00000193`. Applies to: `Alchemy` ## Example If the AAV log contains the following message: `ERROR, Process creation failed; error 0xc1 ERROR, AAV INTERNAL, Process creation failed; error 193` Then you will need to search the MSDN table for `0x00000193`. `0x00000193 ERROR_PROCESS_MODE_NOT_BACKGROUND` : The process is not in background processing mode. ## MSDN All Win32 error codes MUST be in the range `0x0000` to `0xFFFF`, although Win32 error codes can be used both in 16-bit fields (such as within the [HRESULT](https://msdn.microsoft.com/en-gb/library/cc231202.aspx#gt_799103ab-b3cb-4eab-8c55-322821b2b235) type specified in section [2.1](https://msdn.microsoft.com/en-gb/library/cc231198.aspx)) as well as 32-bit fields. Most values also have a default message defined, which can be used to map the value to a human-readable text message; when this is done, the Win32 error code is also known as a [message identifier](https://msdn.microsoft.com/en-gb/library/cc231202.aspx#gt_24c02397-73d4-4bf2-8b93-669ba29d8e94). !!! note See the Microsoft MSDN Table of all [Win32 Error Codes](https://msdn.microsoft.com/en-gb/library/cc231199.aspx). ## MagnumDB (searchable database)
