As mentioned earlier, error code 1603 is most often returned when almost every action in the installation fails. Also, this most often indicates that user actions in the MSI failed.
When we encounter a configuration that no longer works and returns code 1603, the following steps must be taken on this website:
Guide Retry the configuration detailed logging. using steps similar to the methods listed here.
Step i: Create a verbose log file that will be accepted as msi*.log in the %temp% directory the next time the installation package is run.
Step 2. OpenRead the exact verbose log in a text editor such as Notepad and look for the string “return value 3” in order. In almost all cases, this leads us to the section of each verbose log that lists the policies that caused the build to be canceled in the first place.
Step 3: Examine the contents of the log file just above the “return 3” value stream to determine which custom action could have caused the default action to fail. Depending on the type of action that failed, we will ask you to continue here in more detail after debugging.
You may find that often our biggest problem when debugging a failed configuration is to focus on the part of the configuration that is on doesn’t really work. , and this trick along with looking for the value “return 3” speeds up the process pretty well in almost all cases.
Of course, the situation doesn’t work 100% of the time. In particular, when you run the installer on a non-English Windows model, the string “Return Rate 3” is written to the mapping file in the OS language, not English, soString search doesn’t really work.
