It seems the problem was that my system path became too long for Windows to handle: it was <a href="http://blogs.msdn.com/b/oldnewthing/archive/2010/02/03/9957320.aspx">2087 characters long</a> (hat tip to <a href="http://connect.microsoft.com/VisualStudio/feedback/details/501190/receiving-...Title">this article</a>).

None of these solutions solved the problem with my Visual Studio 2012, but I finally managed to fix it by installing the latest Update 4 from the <a href="http://www.visualstudio.com/downloads/download-visual-studio-vs" rel="nofollow">Visual Studio website</a>

blocks|key|246859|text|系统路径变量太长。将当前内容复制到记事本，删除重复输入和不需要的输入，然后复制回path变量。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|246860|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

System Path variable is too long. Copy current content to notepad and remove repeated entries and unwanted enteries and copy back to path variable.

blocks|key|463469|text|当我在已安装了2012的计算机上安装SQL+Server+Express+2014时，收到此错误。我用工具安装了它，这显然破坏了SSMS+2012。特别是当尝试“编辑前200行”时，抛出了错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|463470|使用SSMS+2014似乎工作得很好。|463471|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I received this error when I installed SQL Server Express 2014 on a machine that already had 2012. I installed it with tools, which apparently broke SSMS 2012. Specifically when trying to "Edit top 200 rows" the error was thrown.

Using SSMS 2014 seems to work fine.

blocks|key|246929|text|我的路径似乎也影响了从控制面板\系统\高级系统设置访问高级系统设置，所以我无法编辑路径。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|246930|我必须从windows\system32启动它以显示高级系统设置对话框，然后从那里编辑te环境变量。|246931|最近安装的均值堆栈为我的用户帐户添加了一条path语句。我完全删除了这个设置，然后VS2010和高级系统设置对话框启动，没有问题。|246932|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

My path also seemed to affect accessing Advanced System Settings from Control Panel\system\Advanced system Settings so I was unable to edit the path.

Had to launch this from windows\system32 to display the Advanced System Settings dialog, then edit te environment variables from there.

A recent install of the MEAN stack had added a path statement for my user account. I removed this setting entirely and then VS2010 and the Advanced System Settings dialog started without problem.

blocks|key|463547|text|在我的例子中，这个错误是由于web.config文件中的一个无效密钥造成的。尝试还原上次对文件所做的更改。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|463548|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

In my case this error was due to an invalid key in the web.config file. Try to revert last changes made to the file.

blocks|key|463580|text|BioGeek's+answer修复了我的问题。在我的例子中，系统路径的溢出不仅破坏了visual+studio，还破坏了GUI来改变系统路径本身。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|463581|我收到以下错误:控制面板>系统>高级系统设置。|463582|解决方法是运行c:\windows\system32\SystemPropertiesAdvanced.exe.|463583|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/12750664/2055187^0|0|9|0|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|C|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]]]

<a href="https://stackoverflow.com/a/12750664/2055187">BioGeek's</a> answer fixed my issue. In my case, the overflow of system path not only break visual studio, it also break the GUI to change system path itself. 

I got error on: Control Panel > System > Advanced system settings. 

The workaround is run c:\windows\system32\SystemPropertiesAdvanced.exe.

blocks|key|463631|text|来补充一下BioGeek的答案。您不必删除路径中的条目，您可以通过引入更多变量来绕过字符限制。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|463632|例如：|463633|PATH+=+{1800+CHARACTER+LONG+STRING}{500+MORE+CHARACTERS}|code-block|syntax|javascript|463634|您可以添加一个EXTENDEDPATH变量，如下所示：|463635|EXTENDEDPATH+=+{500+MORE+CHARACTERS}|463636|最后，在路径中引用此变量|463637|PATH+=+{2000+CHARACTER+LONG+STRING};%25EXTENDEDPATH%25;|463638|我建议在path中留出至少100-200个字符的空间，这样你就不必每次安装东西时都要照看PATH环境变量。|463639|entityMap^0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|V|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|W|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|X|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|Y|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|Z|8|@]|9|@]|A|$]]|$1|O|3|P|5|F|7|10|8|@]|9|@]|A|$G|H]]|$1|Q|3|R|5|6|7|11|8|@]|9|@]|A|$]]|$1|S|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|T|$]]

To add to BioGeek's answer. You don't necessarily have to get rid of entries in your path, you can work around the character limitation by introducing more variables.

e.g.

<pre><code>PATH = {1800 CHARACTER LONG STRING}{500 MORE CHARACTERS}
</code></pre>

You would add a EXTENDEDPATH variable, like so:

<pre><code>EXTENDEDPATH = {500 MORE CHARACTERS}
</code></pre>

And finally you reference this variable in your PATH

<pre><code>PATH = {2000 CHARACTER LONG STRING};%EXTENDEDPATH%;
</code></pre>

I'd recommend leaving at least 100-200 characters of breathing room in your path so you don't have to be babysitting the PATH environment variable every time you install something.

blocks|key|247075|text|我也遇到了同样的问题，但我发现"connectionStrings“一定在web.config中的"configSections”之下|type|unstyled|depth|inlineStyleRanges|entityRanges|data|247076|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

i had same problem but i figured out "connectionStrings" must be under "configSections" in the web.config

blocks|key|463683|text|发生此问题的原因是环境变量windows中的长路径仅支持2048个字符。为了解决这个问题，你需要从PATH中删除一些环境变量。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|463684|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This problem occurs due to long path in your environment variable windows supports only 2048 characters.
In order to solve this problem you need to remove few environment varibale from your system from PATH.

blocks|key|463709|text|我在Atmel+Studio7上也遇到了同样的问题。通过删除项目文件所在文件夹中的*.componentinfo.xml文件，解决了这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|463710|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had the same problem with Atmel Studio 7. Resolved by deleting the *.componentinfo.xml file in the same folder as the project file.

When I start up Visual Studio 2010 I often get the error <code>'exception has been thrown by a target of invocation'</code> which prevents me from opening Visual Studio. A reboot of my computer makes the error go away, but a few days later it returns.

What causes this error and how can I get rid of it?

I've found a lot of questions on SO that mention this error when running their code in Visual Studio, but none when opening Visual Studio.
