KnowledgeBase_LamDownloadUpdateInstaller_ pTargetFile_QueryInfo didn't return HTTP_STATUS_OK

The error occurs when the Check for Updates feature is blocked from downloading the installer.

The workaround is to download and install directly from our website:

• https://lambdares.com/support-posts/tracepro-current-release
• https://lambdares.com/support-posts/oslo-current-release
• https://lambdares.com/support-posts/rayviz-current-release

The root cause may be that antivirus or security software is blocking the download.
