RDLC本机错误255 [英] RDLC Native Error 255

问题描述

我有一个使用报告查看器控件在4.5.2上运行的ASP.Net站点.突然在我们的服务器上，我们得到了

I have an ASP.Net site running on 4.5.2, using the report viewer control. All of a sudden on our server, we are getting

编译表达式时发生意外错误.本国的编译器返回值:"255".

An unexpected error occurred while compiling expressions. Native compiler return value: ‘255’.

我们所有的报告都在发生这种情况(大多数报告在一年多的时间里都没有修改过).我正在尝试找出可能发生的变化并导致此变化，并且很快就会出现.

This is occurring for all of our reports (Most of which haven't been modified in over a year). I am trying to identify what potentially changed and is causing this and am coming up short.

我们在Windows Server 2012上.

We are on Windows Server 2012.

我发现一些文章指出了一些安全补丁所引起的问题.我们在服务器上安装了4.6，所以我更新到4.6.1，仍然出现相同的问题

I have found some articles pointing to an issue that occurs with some security patches. We had 4.6 installed on the server so I updated to 4.6.1 and still same issue occurs

推荐答案

原来，如果您已经安装了一些安全补丁，然后又安装了.net 4.6，则会破坏VB编译器.

So turns out that if you had installed some security patches then installed .net 4.6, it breaks the VB compiler.

我必须按照此处的指示删除这两个补丁.

I had to remove those two patches as indicated here.
