Encountered error 1603 while updating sims dating 2 pico

A 1603 essentially means “an error occurred” trying to commit the change, causing to “backout the change”.This type of error is either caused by msi misengineering (most vendor msi are misengineered) or by an “machine specfic issue”.

A way to think about it is the first pass “conditionally installs the change” to the machine while checking the syntax of the command and the second pass “commits the change to the machine”.Because Windows Installer runs only one installation at a time, only one installation is active at any given time and there is only one instance of the indicator objects on any system.The following object indicates an active, incomplete installation on the system.From my experience, the fix is usually trivial once you understand “how to correlate verbose logging results” with msi internals.First, know that “installation” means sequentially processing rows of the Install Execute Sequence table inside the msi database.
