12.1 installer error (Windows 10 Smart Screen)

[Mauricio Moya (Arquesoft)]

When trying to install version 12.1 on Windows 10, it throws an error because Windows Smart Screen is locking the installation. If I disable Smart Screen, then throws an error saying: "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows installer package"

When Smart Screen was active, it warned about the msi has no a valid manufacturer. In the "manufacterer" field it shows "unknown" (where I expected to find "Sparx Systems").

I download the installer again several times, in order to discard a corrupted downloaded msi.

So, I am not able to install version 12.1 in my PC. Any idea? Anybody with the same behavior?

I'm not sure if Windows 10 is already officially supported.

I don't think Win 10 is officially support as Geert notes, but I installed 12.1 yesterday on Win 10 v1511 (Build 10586.14) and didn't have any issues.

You might want to check that the installer is signed by Sparx Systems.
Right click the msi and choose the 'Digital Signatures' tab and then view the certificate.  Mine indicates the following:
Issued to: Sparx Systems Pty Ltd.
Issued by: COMODO Code Signing CA 2
Valid from: 8/13/2014 to 8/13/2017

If the cert is valid the only other things I can think of are:

• That your trusted root certificates are missing the one from the COMODO certificate authority.  This should get installed by default in all Windows versions.  Missing this would likely cause strange errors when visiting web sites or installing other software as well.
• The download link is picking up a corrupted file or corrupting the file

The readme included with the installer does list Windows 10 as supported.

As already pointed out, all installers from Sparx Systems should be signed. And the information described already matches the current certificate being used.

It sounds to me like you have a corrupt download. Not sure why a new download isn't fixing the problem. Maybe it's cached somewhere.

It's possible the corrupted file is in the Windows Installer cache.

Navigate to “C:\Windows\Installer”.  Right click on column headings and add Author.  Look for the Sparx files.

I tried to re-download it again today and now it works. Aparently the installer downloaded yesterday was in fact corrupted and cached. So I tried today after a windows restart and not it works. Thanks everybody

Hmm...

It took me three goes to download the 12.1 installer the other day.

Hey Sparxians!

Can you hash the installer files please and publish the results?

Say MD5 and SHA1...

That way we can do the same at our end, and ensure that the file has downloaded correctly BEFORE we try to install!

PS. These are the MD5 and SHA1 results for the most recent installer that I've downloaded:

[Eve]

Shouldn't the signature on the file do exactly that without requiring users to manually run a hash on the downloaded file?

[AndyJ]

Good question.

What does the user see if the file has not downloaded successfully?

This is the nice thing about Windoze: just a file. You might download two more times and compare the files. If you find two identical ones then chances are high (but not 100%)  they are complete.

Hello  AndyJ,

If the installer is correctly downloaded, its degital signature is correct. So,

right-click the installer file on Windows, then select 'Properties'
- the 'Digital Sigunatures' tab exists and the Sparx Sigunature is OK, the installer is correcty downloaded
- the tab does not exist or the Sigunature is not OK, the installer is corrupt.

HTH,

[AndyJ]

OK.

Subtle but good.

If there is no digital signatures tab, then the file has not downloaded.

Of course the real elephant in the room, is why these files are frequently not downloading properly.

Sparx server timing out maybe?
