Hi Xuyingkui,
Have you upgraded the MATLAB installation since you were running adiabat_1ph 3? If so, the perl.exe executable will have moved. You can see the error message by opening cmd.exe, navigating to the windows_alphamelts_1-4 folder, and typing 'install.command'.
If that is the problem then try right-clicking the install.command file and choosing 'Open with...', or similar. Navigate to the perl.exe file, which will be somewhere like C:\Program Files\Matlab\Rrelease\sys\perl\win32\bin\perl.exe - then continue as before. That should update the .command file association, whilst keeping the same Path variable etc.
Hope that helps.
Paula
