I have observed few things in log file MSI (C) and MSI (S). after installing MSI file in test machine what is that meaning of it? How does they works ?
Pleas help me can anyone
please provide the software and the parts of the log in question.
Also you could review the manual pages of the developer.
The MSI SDK has information on this. For your question, MSI(C) indicates the MSI installation Client process and MSI(S) indicates the MSI Server process. The information in the logs is quite complex and reflects the different stages of the install, specifically the Immediate and Deferred installation sequences. During the Immediate sequence, the MSI installer builds a list of tasks to execute, based on the standard and custom actions in the InstallExecute table. Any "immediate" custom actions are executed as soon as they are encountered, whereas any "deferred" custom actions are just recorded for execution in the task list. Once InstallFinalize is reached, the task list is then executed and changes are made to the system. If anything goes wrong at this point, the changes are reversed. During task execution, actions do not have access to the majority of properties.
If you have a specific question about a specific logfile, post the section of the log here, and we can try to explain the meaning.
