32bit版と64b​it版の両方をインス​トールすることはでき​ますか？

R2015bの64bit版MATLABをWindows7上で利用しています． あるドライバーを使用しようとしたところ，32bitのMATLABしかサポートしていないことが判明しました． そこで，64bit版がインストールされているWindows7に32bit版を追加インストールしたいのですが，両方を同時にインストールすることは可能でしょうか（ライセンスの面，安定性の面）． 使用する際は，どちらか一方のみを起動するものとします．

Is it possible to install both 32bit version and 64 bit version?

The 64bit version of MATLAB R2015b have been available on Windows7. I tried to use a certain driver, we found that not only supports MATLAB of 32bit. So, I want to install an additional 32bit version Windows7 the 64bit version is installed, Is it possible to install both at the same time (license of the surface, the stability of the surface). In use, it is assumed that you start either the only one.

Yes, the license and stability are fine if you install both.

There are a small number of difficulties to watch out for when you have multiple versions on a system:

• Only one of the versions can be the default version when .m files or .slx or .fig files are double-clicked in Windows Explorer. There is no way in MS Windows to designate some .m files to open one version of MATLAB and other .m files to a different versions of MATLAB. This applies to different releases of MATLAB as well.
• Only one of the versions can be invoked by Excel or other programs that use MATLAB Engine. You can control which version is used; see http://www.mathworks.com/help/matlab/matlab_external/register-matlab-as-automation-server.html . This applies to different releases of MATLAB as well.
• You might have to re-do "mex -setup" or "mcc -setup" when you change versions, as the same configuration file was used for 32 bit and 64 bit. If I remember correctly, they fixed this before R2015b so it might not be a problem for you.

Thank you for your kind answer and translation. I'll try to intall both.

You can install both 32 bit and 64 bit on the same computer. I have this. I believe it uses only one license activation.
