Release Notes for Update 1 for RTX64 4.5.4

This update to RTX64 4.5.4 resolves the issues listed below.

Issues Resolved

Resolved a memory allocation thread contention issue encountered under stress conditions. (18667)

When the TCP/IP Stack MaxSockets value is set to 32765, you may need to allocate more memory to the Stack. To do this, increase the Minimum size for external MSpace (kilobytes) on the Manage Memory page in the RTX64 Control Panel. We recommend allocating at least 19498.2421875 KB. When not enough memory is allocated for the Stack, performance issues can occur. (18215)

RTX64 Runtime is incompatible with Windows 11 24H2 OS Build 26100.4349. If that build is installed, you must install Windows 11 24H2 OS Build 26100.4351 to use RTX64.
Upgrading a machine to Windows 11 24H2 deletes the RTX64 boot configuration. For more information, see the TechNote RTX64 Boot Configuration Missing After Upgrade to Windows 11 24H2, available on the Support Site.
Some RTX64 tools do not scale properly on 4K monitors. (18010)
You may encounter a timeout error when attempting to start the TCP/IP Stack when the MaxSockets value is set to 32765. See Notes above. (18220)
After you install RTX64 Merge Modules on Windows 11 and run the sample Advanced Installer project file, RTX64Sample.aip, it prompts you to select prerequisites to install. If you select Windows update prerequisite KB3033929 and click Next, an error appears that the prerequisite was not correctly installed. You can disregard this error. The sample Advanced Installer file will install and run without the prerequisite. (18351)
