How to install:

1. Install gzip

   Click gzip-1.3.12-1-setup.exe and install gzip. 
   
   For example, after install it, gzip.exe is under C:\Program Files (x86)\GnuWin32\bin\
   

2. Install Net_Diff

   a) If you have installed MATLAB R2017a or MATLAB Runtime version 9.2 (R2017a) on your computer.

   Open /for_redistribution_files_only/ and click Net_Diff.exe
   

   b) If not.

   Open /for_redistribution/ and click Net_Diff_Installer_web.exe to install MATLAB Runtime and Net_Diff.exe
   
   Please keep your computer connected to internet while installing.
   
   It will take a few minutes to download MATLAB Runtime, please be patient.
   
   If error occurs in downloading MATLAB Runtime 9.2, please download or update it by hand from:        
   https://ww2.mathworks.cn/products/compiler/matlab-runtime.html
   
   As space is not allowed for the directory of EOP file, so please do not install Net_Diff under a directory that contains space, such as C:\Program Files\. After finish installing, you can find the execute file from the installed program directory, for example C:\Net_Diff\application\. 
   

3. Set environment variables

   This step is to automatically unzip the downloaded file and convert the crx file to rinex file if you want to download or update files in Net_Diff. 
   
   To do this, please add the path of gzip.exe (C:\Program Files (x86)\GnuWin32\bin\) and crx2rnx.exe (C:\Net_Diff\application\) to the PATH of system environment variables on your computer:
   
   My computer-->Properties-->Advanced system setting-->Environment variables-->Edit the PATH environment variable-->Add path
   
   If you have problems in setting the environment variables, you can simply copy C:\Program Files (x86)\GnuWin32\bin\gzip.exe to C:\Net_Diff\application and run Net_Diff from C:\Net_Diff\ application. 
   When running Net_Diff from the Windows Start or the Desktop, you should also copy C:\Program Files (x86)\GnuWin32\bin\gzip.exe and C:\Net_Diff\application\crx2rnx.exe to the folder of C:\Windows\System32 or Desktop.
