    When installing Symantec DLP 26.1 Beta, the installation fails with the error "Error unpacking reinstallation resources file: ReinstallationResourcesUtility returned exit code -1." The issue occurs on Windows Server 2022, even when running the MSI directly with a short install path, redirecting TEMP/TMP, disabling Windows security features, and after installing the latest Visual C++ Redistributable for Visual Studio 2015–2022 and rebooting. Is this a known issue with DLP 26.1 Beta on Windows Server 2022, and is there any workaround or fix available?
