Can't launch the Modelsim-Altera Software after the compilation

Problem:

My OS is Windows 7 64 bit. I'm using Quartus II 15.0 Web Edition, and Modelsim 13.1d. I can't launch the Modsim-Altera software after the compilation and the compilation is no error and warning.

I checked Tools>Options>EDA Tool Options:

F:\program file(x86)\15.0\modsim_ase\win32aloem,I can't launch the ModelSim-Altera software. The path to the location of the executables for the ModelSim-Altera software were not specified or the executables were not found at specified path...

I trid to change and add the path:"\" or "/" and cut the modsim_ase files to outside of the program file(x86) files.but don't work.

The way of solving the problem:

The path:"F:\program file(x86)\15.0\modsim_ase\win32aloem" includes a blank space,in other words,program file(x86) contains a blank space or '(' and ')'.You should change the path:for example,

"F:\programfile\15.0\modsim_ase\win32aloem\",

"F:\altera\15.0\modsim_ase\win32aloem\",

"C:\altera\15.0\modsim_ase\win32aloem\"

I try to re-install Quartus and Models in a directory and now are both in folder 15.0 and the path of simulation assigned is:

F:\altera\15.0\modsim_ase\win32aloem\".It does work!!!

note:

1.The install and project directory doesn't have blank space.

2.The default directory path is "C:\altera\15.0".You'd better only change the 'C' to 'F'or other disk.
