SCUP 目录导入错误

试图让 SCUP 在系统上运行但遇到一些困难。SCUP 安装得很好，我已经按预期配置了组策略和 CA 发布的证书。但是，当我尝试导入任何目录时，错误如下：

Launching expand.exe  with arguments: -R "C:\Users\USER\AppData\Local\Temp\2\\fdushzom.4gk\AdobeFlashPlayerCatalog_SCUP.cab" -F:* "C:\Users\USER\AppData\Local\Temp\2\\iegdaw4t.ar4"

SCUP 与 WSUS (Server 2012 R2) 安装在同一台机器上，是 SCCM 的 SUP。WSUS 正在为 SUSDB 使用 SQL Server 2014 群集。如果需要更多环境信息，请告诉我。
