Built-In Signed EXE installer blocked by Browser

Tue Sep 06, 2022 3:13 am

Our AdvancedInsaller is setup to sign EXE from certificate store with built-in selection.
Our customers will download our EXE installer (either as an exe or zipped exe).

Our build output:

Code: Select all

Building package: 
Prepare build
Detecting MSI incompatible resources
Preparing files
Creating CAB file(s)
Signing CAB file(s)
Creating MSI database

Signing MSI
This file was signed with the certificate: FtCert_2022-8-6_11-27-58
Creating EXE file
Signing EXE file
This file was signed with the certificate: FtCert_2022-8-6_11-27-58
Validating MSI
When we copy the EXE or zip file to the cloud-server then customers download it then browsers blocks the file.
We would expect that the browser would recognise the valid signature and allow it to be downloaded...

Please advice how to workaround this issue (so that no workaround action is required by customer)...

Hello and welcome to our forums,

I'm not sure why this happens. Can you please send us a screenshot with the error message thrown by your Browser when you try to download the installer? Also, can you tell us what antivirus program do you have installed on your machine (if any)?

It would be very useful if you could isolate the behavior in a detailed step by step test case which we can follow and test on our side.

Also, what certificate did you use to sign the installer? It is from a trusted authority or it is a self-signed certificate?

Best regards,
Liviu
