关于“MCR instance is not available”的问题。

关于“MCR instance is not available”的问题。
基于COM组件技术，使用VC和MATLAB混合编程的应用软件，当在另外一台机子上发布时，怎样脱离MATLAB的运行环境？
我查相关的资料说由于matlab7.X系列的缺陷，与matlab混合编程的应用程序不能脱离matlab环境，所以我就在目标计算机上装了matlab，但是发现，即使装了matlab后，并对组件进行注册，运行时仍然提示：“MCR is not available”。
请高手指教，这是怎么回事，有什么办法解决。

Subject:
Why do I receive an "MCRInstance not available" error when deploying an application built with MATLAB Compiler 4.0 (R14)?

Problem Description:
I am trying to run a stand-alone application that was generated with the MATLAB Compiler. However, I receive the following error message when I call the program:

MCRInstance not available


Solution:
This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

This error may occur if the executable file cannot find either the required MATLAB run-time libraries or the CTF archive for your application.

First, check your system path to verify that the MATLAB run-time libraries can be found. If you are testing your application on a development Windows machine, confirm that $MATLAB\bin\win32, where $MATLAB is your root MATLAB directory, appears on your system path and ahead of any other MATLAB installations.

If you are working on a target Windows machine, verify that $MCR_ROOT\runtime\win32, where $MCR_ROOT is your root MATLAB Component Runtime directory, appears on your system path.

For help viewing or modifying the system path, see:

http://www.mathworks.com/support ... ml?solution=1-15ZLK

Next, verify that the .ctf archive file that the MATLAB Compiler generated in the build process resides in the same directory as your program's executable file.

您说的个资料我也看过，但是还是解决不了问题，难道就只能等mathworks公司改进产品以后才能用吗？
你们遇到这样的问题是怎么解决的，请高手耐心讲一下吧，小弟愁坏了！！！

具体这个问题我没有碰到过

一般碰到这类问题i要嘛是根据提示升级到相应版本或者更高版本
要嘛就是根据下面的提示进行设置或者修改，mathworks给出来的方案应该是有效的

首先应该分别使用mwregsvr和regsvr32注册你的COM组件DLL。
然后把你的组件的CTF文件放到你编写的可执行程序目录下 ，这很重要，否则就会出现MCR instance is not available。

xl_43400说的对啊
我用7.0就可以啊 没有出现这个问题啊
