MySql Workbench安装程序需要安装Visual C ++ 2015可再发行组件包，但已安装 [英] MySql Workbench installer requires Visual C++ 2015 Redistributable Package to be installed, but it already is installed

问题描述

我在网上到处都看过，但似乎没有人能够解决此问题.

I've looked everywhere online, but it doesn't look like anyone has been able to resolve this issue.

当我下载并尝试安装MySql Workbench时，系统提示我安装要安装的Visual C ++可再发行组件包(2015).然后，向导将我直接带到此网站进行安装.

When I download and try to install MySql Workbench, I get prompted to install Visual C++ Redistributable package (2015) to be installed. The wizard then takes me directly to this website in order to install it.

但是，每当我尝试安装其中任何一个时，它只会告诉我它们已经安装.

However, whenever I try to install either, it just tells me they're already installed.

在搜索了大约一个小时后，我发现其他人遇到了这个问题，显然已经由按照本网站上的说明进行操作.我下载了instaedit并按照说明进行操作，但是仍然出现相同的错误.

After googling this for about an hour, I found some other people had this problem which apparently was resolved by following the instructions from this website. I downloaded instaedit and followed the instructions, but I continue to get the same error.

我已经在这里待了两天了，我会发疯的.如果有人可以帮助我，我将非常感激.我正在使用Windows 10，

I've been at this for two days now and am going to go crazy. If someone can help me with this I'd be very grateful. I'm using Windows 10,

推荐答案

事实证明VC ++ 2017可再发行产品是罪魁祸首，因为它们删除了VC ++ 2015可再发行产品所使用的注册表项. 请参见此Microsoft开发者社区页面解决方案(TL; DR；您必须修复 VC ++ 2017 可再分发文件，因为这将恢复丢失的2015年注册表项).

It turns out that VC++ 2017 redistributables are the culprit because they delete the registry keys used by VC++ 2015 redistributables. See this Microsoft Developer Community page for solution (TL;DR; you have to repair VC++ 2017 redistributables as this will restore missing 2015 registry keys).

此过程是如Eric描述:

从本质上讲，这些步骤是:转到控制面板"中的程序"(或Windows 10的设置"中的添加或删除程序")，找到Microsoft Visual C ++ 2017 Redistributable，单击它并选择更改/修改"，然后选择修复".

The steps are essentially: go to Programs in Control Panel (or "Add or Remove Programs" in Windows 10's "Settings"), find the Microsoft Visual C++ 2017 Redistributable, click it and choose Change/Modify, then choose "Repair
