Description:There are multiple fixes included Update Agent 6.3 P-1 (R2) (Windows). They are:

  • The agent does not register on non-English platforms.
  • Non-Administrators will receive an access denied error message when opening the control panel or when viewing the current status of the agent in the control panel in most circumstances
  • An error message appears in the event log concerning a missing assembly. PatchLink KB408
  • The DWORD evaluation within the detection agent works for fingerprint evaluations.
  • Detection agent would incorrectly read registry keys for file path locations if a semi-colon was contained within the value for the registry key.
  • In some circumstances (like an agent going through a VPN and a proxy, or 2+ proxy servers, etc.) would report its IP address as or
  • If an inventory item on WinXP SP2 contains an invalid XML character (&, <, >, etc.), an XML Parser error would be popped up to all logged on users. Log contains XMLDeltaParser error.
  • The detection agent no longer uses the proxy registry keys if they exist from older versions of the agent when the agent was upgraded.
  • The agent will resume communication to the server on its next communication interval when it has failed to communicate to its entire list of fast path servers.
  • The Agent Installation Guide proxy section has been updated
  • If remote registry or performance counters are disabled then the agent will attempt to get the system uptime value for 30 seconds instead of 300 seconds and if it is unable to obtain the value then it will clear the dirty-r and dirty-c state values. In this system configuration the agent will not be able to track if the system rebooted upon service startup.
  • Caching enhancements have been implemented in to the agent to increase the ability of the agent and caching servers to cache packages from the 6.3 Update Servers.
  • The detection agent will handle the condition when one of the system’s volumes are not accessible when trying to access the volume on Windows NT/9x.
