此版本的IDM不支持该类下载，请尝试将IDM更新至最新版本

平时可以正常使用，谷歌浏览器内用IDM下载突然提示不能用了，但是复制链接到IDM中新建任务不影响使用，推测可能和谷歌浏览器更新有关，打开谷歌浏览器的扩展工具，移除IDM Integration Module。

然后打开IDM安装目录，找到IDMGCExt.crx，直接拖拽到浏览器扩展工具界面，再去下载就不会提示版本不支持了。

原因  在于禁用扩展自动更新，扩展和软件版本要一致。 How to disable Google Chrome extension autoupdate

Solutions I've found for this:

1. Disabling a concrete extension update

That's what I wanted!

You can do this by editing the extension's manifest.json file:

• On Windows: C:\Users\<USERNAME>\AppData\Local\Google\Chrome\User Data\Default\Extensions\<EXTENSION-ID>\<VERSION>\manifest.json (find out the extension's ID by enabling Developer Mode in the extension settings page)

• On MacOS: Open /Users/USERNAME/Library/Application Support/Google/Chrome/Default/Extensions/EXTENSION-ID/VERSION/manifest.json in a text editor.

• On Ubuntu for Chromium: ${HOME}/.config/chromium/Default/Preferences

In this file, set the "update_url" property to something invalid like "https://localhost" for example. For the given url, it makes auto-updating that extension as simply impossible.

2. Disabling all Google Chrome extension updates

• For any OS: Just type chrome://plugins/ at address bar and turn Google Update plugin off. Source: How to disable Google Chrome auto update?

• For Windows OS: Set Registry values:

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Update]
"AutoUpdateCheckPeriodMinutes"=dword:00000000
"UpdateDefault"=dword:00000000
