Dell SonicWall causes installation to freeze/fail

Postby langoroth@gmail.com » Thu Feb 02, 2017 4:51 pm

I've run into a weird situation and I am looking for guidance.

I have the option: Automatic updates (every time setup is run) checked.
So when my installer is run, it goes out to check for the latest version.

However, there is a firewall program called SonicWALL that will block this request. It thinks it is a Trojan (and I can't find anyway to tell Dell that it isn't).
When it blocks this request, It causes the installation to crash.

If I have the client turn off the internet, then my software will install properly.

My software is digitally signed and it is released as a single .EXE

On the MSICode tab, there is an updates tab, but I am unable to determine if there is a way to add an error trap so that if the update request is blocked then it just continues with the regular installation.

Any help would be appreciated.

Thank you.

Dear User,

unfortunately there isn't so much to do. Most AV's today are a cure worse than the disease.

What you are reporting is a classic FALSE POSITIVE and your installer crashes because the AV alters its process. Due of this, there isn't any approach that can be used to prevent this to happen ... unless you don't remove the AV.

The only option is to contact the AV vendor for white listing your package.

Hope this helps you.
