I have installed 64 bit matlab in place of 32 bit, but now my old programs are not running

I have installed 64 bit matlab in place of 32 bit, but now my old programs are not running on 64 bit which were executed on 32 bit,what is the solution?

Answer 1

[Azzi Abdelmalek]

What do you mean by my old programs? m-files or simulink models? Check if the toolbox used by your script are installed by typing in Matlab Windows command

ver

If some of your simulink models are not working, check If they use a compiler, for 32 bit the default compiler is lcc, but for the 64 bit you have to install one

[Kirti Wanjale]

I mean to say the .m files

[Azzi Abdelmalek]

Can you post one of your error messages?

Answer 2

[Andreas Goser]

Here are a couple of generic ideas why this happens. Of course only error messages and code examples can help us to help you

• MEX files - You need MEXW64 files instead of MEXW32. Regenerate them from source code if needed
• You may also have a different OS, like Win7 64 bit instead of WinXP 32 bit. See for all OS related opeations
• You may also have different MS Office products - same story

We cannot post an advice based on the information "programs are not running" and even the detail, that you mean "M-files" is not sufficient. I suggest to give us a chance and post the concerned code and either the error message or the difference between your expectations and the obtained results.
