我的管理员遇到了一个大问题，我将他们的困境转达给 SO：
我们有一个遗留数据库应用程序（用 Progress 4GL/OpenEdge 编写）调用WordPerfect X3以生成报告。WordPerfect 可执行文件的路径是硬编码在数据库应用程序中的，以及要插入数据库的扫描 PDF 的位置，我们无法修改程序。
我们的大多数工作站已成功从WinXP迁移到Win7，并且旧版应用程序运行良好，直到它尝试调用 WordPerfect，说它找不到可执行文件（即使 X3 安装在 WinXP 上使用的完全相同的路径中）.. . 与扫描的文件夹相同。
有什么建议么？
更新：
我今天早上用你们提供的各种建议帮助我的管理员……我们检查了文件权限，用十六进制编辑器查看了编译的（.r）文件（感谢@Tom和@Ernest），并在使用 Notepad++ 的所有源代码 (.p) 中的文件。
这是我发现的： 该程序不是直接调用 WordPerfect（正如我最初被告知的那样），而是使用 DDE。这是 Progress 4GL 产生的错误消息：
我知道 DDE 和 Win7 存在问题，所以我想知道是否有解决方法，可能需要修改注册表项或其他影响。
我从下面的源代码中摘录了一段，希望有人能认识到发生了什么（我不熟悉 Progress 4GL，所以对我来说都是希腊语）：
