    SW ver 15.7.4 - download problems

    It was with eager anticipation that I tried to download the newest VCDS version (ver 15.7.4). My laptop is a surface pro3 without any nannyware and running bog-standard windows 10 (64 bit ver). However, much to my disappointment, after waiting for the file to download, I got the following error message



    Tried multiple times with the same result. Then tried on my PC (windows 7 - 64 bit). Still the same error message. Given that I've read at least one post on the forum saying that they were able to download 15.7.4, I can only assume that my issue is with 64 bit machines - is there a known problem with this latest version?
    Don

    EDIT: Found a work-around for this error as follows:

    Step1 - find the downloaded file
    Step2 - right click on the file and select properties
    Step3 - next to the words "This file came from another computer and might be blocked to help protect this computer" click Unblock
    Step4 - Click OK

    We've had a similar report yesterday, also from a Windows 7 installation - though based on a different certificate. Interestingly enough, on my Windows 7 Pro test machine, I don't have this problem BUT I do get a similar report for the latest VirtualBox installer - which has a valid signature. That leads me to assume this isn't a problem with our signature but something with the latest Windows 7 iterations.

    After some digging, I came across this note...

    https://forums.virtualbox.org/viewto...p?f=6&t=75929#

    ...and specifically this MS article...

    https://technet.microsoft.com/en-us/...y/2880823.aspx

    ...and then checked our signature. Guess what? SHA-1



    I'll look into this today and get back to you with more details.

    There should be a way to re-issue (technically it's called re-key) the existing certificate with sha-2 algorithm.

    For that, I think you have to contact your certificate vendor.

    Sebastian: Thanks for the heads-up. Interesting problem! And yes, sha1 too in the English screens



    Something that needs to be fixed eventually (I guess), but the work-around seems to be OK, so not a big problem (I think)

    Don, can you download the following file and let me know if this fixes the error message? This is a German version of VCDS, so don't actually install it - but it should be enough to test the signature. It is double signed, SHA1 & SHA256.

    @Steve, thanks for the note. The certificate used for the non-US versions was 256 already but I hadn't updated signing tool in a while and it was sticking with SHA1. *D'Oh*

    Sebastian: Good morning! Alas the same error message in this file! pictures below. Why does windows report multiple copies of the sha 256 signature?
    Don

    Edit: Odd thing! Unlike the previous English version which was not accessible (as an executable file) without my fix above, and notwithstanding the message about blocking the program in my picture below, I can access your German version (without the fix) and run it. I didn't actually install this morning's file, but the correct screens opened to install the program - go figure!!

    This should be fixed now.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Uwe: dynamic for the latest version (just downloaded) is a little changed! File downloads OK and passes security scan. Can be executed OK, so no problems there. Still get the odd message about being blocked and the double entry for sha256 - but these don't matter I guess because the file executes OK (just housekeeping issues for MS Windows- I guess)

    Don, I don't see any double sha256 for the the latest VCDS-Release-15.7.4-Installer.exe

    Code:
    signtool verify /all /pa .\VCDS-Release-15.7.4-Installer.exe
    File: .\VCDS-Release-15.7.4-Installer.exe
    Index  Algorithm  Timestamp
    ========================================
    0      sha1       Authenticode
    1      sha256     RFC3161
    
    Successfully verified: .\VCDS-Release-15.7.4-Installer.exe
    The latest VCDS-DRV-15073-Installer.exe is also good.

    Code:
    signtool verify /all /pa .\VCDS-DRV-15073-Installer.exe
    File: .\VCDS-DRV-15073-Installer.exe
    Index  Algorithm  Timestamp
    ========================================
    0      sha1       Authenticode
    1      sha256     RFC3161
    
    Successfully verified: .\VCDS-DRV-15073-Installer.exe
