InstallShiels can't support Windows11 22H2(SAC) ?

Hi

Windows 11 22H2 add a new significant protection from malware (SAC), and the apps is packaged by InstallShield will be blocked by SAC.

Will you have any schedule to support SAC in the next upgrade?

Thanks.

Does your application and msi have a digital signature?

Yes, my files have the digital signature.

So my files can work if SAC enabled.

But the installation procedure will be blocked by SAC.

And your setup itself is also signed with a trusted signature? According to the document linked in the original post:

If the security service is unable to make a confident prediction about the app, then Smart App Control checks to see if the app has a valid signature. If the app has a valid signature Smart App Control will let it run. If the app is unsigned, or the signature is invalid, Smart App Control will consider it untrusted and block it for your protection.

And also:

"I'm an app developer, how can I get Smart App Control to not block my app?"
The simple answer is, sign your app with a valid certificate.

So this might be a bug in the pre-release version of SAC. Please give feedback to Microsoft:

  1. In Windows, go to the Feedback Hub. (from the Start menu or press Windows key + F).

  2. When you get to Step 2 - Choose a category, select Security and Privacy - Smart App Control.

Hi

I suppose the blocked issue occured during the app is installing.

Installshield installation procedure will generate some temporary files during installing and these files don't have a valid signature possibly .

Then the installation procedure is blocked by SAC.
