Upgrade to version 10.4 (from any other version) stalls on Windows 2003.


A process that verifies the server's condition before the upgrade and detects possible issues stalls when checking the free memory.


To resolve the issue, the following actions are required:
1. Download the utility "process explorer" and launch it.
2. Start the upgrade and wait until the "examine_launcher" process spawns a child process called "wmic.exe" with the command line string "OS get FreePhysicalMemory."
3. Kill that child process, and the upgrade will continue.
