WIA Scanning issues on XP
提问by Chrisjan Lodewyks
I have a WPF application that I am using to scan documents to a users mailbox etc.
我有一个 WPF 应用程序，用于将文档扫描到用户邮箱等。
When debugging the application on my 32bit Windows 7 professional machine all goes according to plan, as well as the deployed version on another 32bit Windows 7 machine.
在我的 32 位 Windows 7 专业机器上调试应用程序时，一切都按计划进行，以及在另一台 32 位 Windows 7 机器上部署的版本。

win 7 版本在 xp 上不起作用 - 您可以尝试为 XP 下载此版本。

To make deployment simpler, turn the files from Richard Friend's Answer into an Inno installer.

I just did that since I have to deploy this in a small office and it works. I'm putting it on x86 machines only. You might have to tweak it a bit to work on x64 machines.
我只是这样做了，因为我必须在一个小办公室中部署它并且它可以工作。我只把它放在 x86 机器上。您可能需要稍微调整一下才能在 x64 机器上工作。
