我使用 pyinstaller 和 Inno 编译了一个桌面应用程序，但在上传 pdf 文档时始终存在问题。当该应用程序安装在其他Windows PC上时，除了上传要存储在sqlite数据库中的pdf文档的功能之外，所有功能都可以正常运行。但是当应用程序安装在编译它的PC上时，所有功能都可以工作。我还使用 --hidden-imports 作为 pyinstaller --hidden-import PyPDF2 --hidden-import pdfplumber --hidden-import Pillow The_Hr.py 但这从未解决问题。
我多次尝试编辑下面的代码摘录，但似乎没有任何效果，请问有什么帮助吗？

这很难回答，我们需要 MRE：https://stackoverflow.com/help/minimal-reproducible-example
一些猜测：
请粘贴 Inno Setup 脚本，以便我们可以看到安装程序实际在做什么。
