<NMAKE : fatal error U1073: 不知道如何生成“D:\Program” Stop.> when generating a protected model or s-function.

When I was generating a protected model from a simulink model, a following error occured.

Code generation and compiling were done, but NMAKE error occured and no protected model generated.

The same model could be transfered into protected model just 2 days ago! But it doesn't work since yesterday!

I used my partner's computer, but it did not work.

I changed the compiler, but not worked neither.

I use a Matlab 2014a academic version.

Please help me!!! Thank you all.

Luckly I find the reason just right now!

It is because there is a space in the install directory of Matlab ("Program Files").

Change the file name into "Program_Files" and it works!

But I am still confused why it did work 2 days ago when there was also a space in the directory???

which folder is in the install directory ?what is the file name?
