    Hello,
    While getting contents of Sentinel images I’ve got an error message that

    file /home/user/sarproz/kroodi_160/../SRTM/N59E024.hgt is missing. Trying to download it
    
     file /home/user/sarproz/kroodi_160/../SRTM/N59E024.hgt correctly downloaded
    
     An error occurred and was saved in the file lasterror.mat, directory /home/user/tools/sarproz_compiled
    
     If you need assistance, please include the file lasterror.mat
    
     You may include also file 02_Feb_2017_09_39_25_sarproz.log
    
     Here a glimpse:
    
    Invalid zip file "/home/user/sarproz/SRTM/N59E024.hgt.zip".
    

    File itself actually exists, but I don’t know how to check its validity.

    Hi Jaroslav
    sometime in December the SRTM ftp download changed the format and we uploaded the new code on Dec 12.
    You have to update your software version. If you cannot use the “manage version” module, write an email to me, and I’ll send you a link

    Hello, I have the same problem, I update the software several times by “manage version” (or try because I still have compile version from 29.oct.2016) and the problem with the Invalid zip file “E:\IMAGERY\SRTM\N18W070.hgt.zip”.

    If you check your failing SRTM file,
    it should be very small, you can open it with a text editor, you will see it is actually an html file, not a zip one
    delete it and all similar files, that will solve the problem (the software will download them automatically when needed)
    if you are not sure about which file is good, which one is not, delete all files in the SRTM folder
