matlab卸载后重装不上了怎么办

Question

当我打开安装程序时会出现以下提示：
The installer cannot read the mwinstall.dll file, This is probably due to a CD reader which can
only read files with an eight.three naming convention.

ok

用的是xp系统，请问哪位高人指点一下，最好不要重装系统。

Answer 1

安装MATLAB7时弹出以下警告对话框，显示“ The installer cannot read the mwinstall.dll file, This is probably due to a CD reader which can only read files with an eight.three naming convention. Please see the technical support page at www.mathworks.com ”
网上有很多人说解决方法如下，这其实是Matlab的一个BUG，一般情况文件解压是把临时文件放到C:\Windows\Temp下，但Matlab却是放在了根目录，所以只要把临时文件夹移到根目录下就可以解决问题了!!
解决方案：把Matlab放在C盘,右键点击“我的电脑”->“属性”->“高级”->“环境变量”，把TMP和TEMP的值都编辑为C:\Temp ,同时在C的根目录下建立一个Temp文件夹!然后解压缩.然后点击安装就可以了!!不过安装后,最好还是把原来更改了的设置再改回来!把 C盘下的Temp文件删除就可以了.
我试用了没有用！后上网看看，上一韩文网站上以现了解决问题的加减法，大家可试试

很多人下载的安装文件都是放在下载工具的下载目录内，甚至是中文录内，将下载目录改为数字或英文试试，要是成功啊请留言告诉我一下！

原文如下：

Problem Description
Why do I get the following error after downloading MATLAB R12 and running the installer?

The installer cannot read the mwinstall.dll file that is probably due to a CD reader which can only read files with an eight.three naming convention. Please see the technical support page at www.mathwoorks.com for assistance.

Solution:
This issue has been addressed in the R12.1 Professional Version of MATLAB and in the R12 Student Version of MATLAB PC installer.

This error is caused when trying to run the PC Installer in a directory that contains a space in it or in a directory whose parent directory contains a space. For example, downloading and installing files from the following location would cause this problem:

C:\Program Files\temp

If you encounter this problem, you will NOT have to redownload the files. To correct this problem, there are two solutions:

1) After running the Installer.exe file the first time, several files are extracted and the setup.exe file is automatically implemented. The use of setup.exe causes the problems with the missing DLL file. After running the Installer.exe file, a file called jins.exe will be created within the temporary directory. If you run the jins.exe file, you should not encounter the problem relating to the missing DLL file.

2) Move all the downloaded files into a directory that does not contain any spaces within it or its parent directories.

For example:

C:\temp\downloads\matlab\R12

Answer 2

请重新安装，安装步骤如下：
1.打开文件，你会发现有2个文件夹，打开第二个文件夹；
2.点击安装程序，红色圈标记；
3.不使用internet安装；
4.点击是；
5.去一开始看到的第一个文件夹寻找下图所标记的文件，打开就是序列号；
6.新手的话就安装典型，不需要自定义；
7.安装路径就自己弄个地方安装，可以直接是安装在D盘下；
8.许可证文件如图所示（见网页）；
9.安装，然后就是漫长的等待；
10.安装完成；

Answer 3

我试过了，点uninstall是卸不了的。所以我用shift+del把matlab文件夹里的东西给全删除了。
然后，开始、运行、regedit,ctrl+f查找，在几个目录下会找到matlab关键字的东西，把它们给删除了就行了。
然后就重启重装吧！
