Preflight window does not work in Windows 11
STEPS TO REPRODUCE
- Install Acrobat DC on Windows 11 using Creative Cloud client.
- Open PDF
- Go to Print production tools.
- Click Preflight
- Windows 11 64-bit.
- Have tried physical machine and virtual, Windows Pro and Home, Service pack 1000.22638.1000.0 and 1000.22636.1000.0.
- Preflight window opens, listing various preflight options & profiles.
- Preflight window (without profiles) opens in background, but is immediately followed by an error message: "Unable to copy the user specific preferences:" and an OK button. Clicking the OK button closes the Preflight window.
Trying repeatedly to open the Preflight panel eventually leads to an empty Preflight window with no profiles. It seems whatever snag the system gets stuck on, it only attempts each step once then gives up.
I have tried resetting Acrobat. Completely uninstalling. Installing in a fresh, clean virtual machine running Win11. Removing all user settings in AppData\Roaming, Local and LocalLow. Nothing.
The only thing that "works" is running Acrobat in a virtual Windows 10 machine. Which makes me conclude the problem is an incompatibility with Windows 11…

Thanks @Jaagup Susi – that workaround seems to have fixed it for me. I'm still lacking a lot of profiles in the lists but I think those are the ones it failed to copy before. I'm sure they'll all come back once I delete the app settings and start fresh.
Too bad the "solution" here seems to be a the expense of security. PDFs are pretty powerful these days and therefore also pretty powerful attack vectors. I'm not sure what protections I'm giving up by disabling these options…
I just hope Adobe get their sh!t together and make an actual fix at some point. Instead of just continuing to add bling and useless new features, I'd rather they made sure the functionality that's already there worked first… But maybe that's just me.

Go to Preferences > Security (Enhanced) and disable:
1) Enable Protected Mode at startup (Preview)
2) Enable Enhanced Security
and the problem should be fixed. Saw this solution in some forum and it solved this problem perfectly. If I remember correctly, Adobe support had suggested this.

Thank you, Mikael, for the analysis and report. I came here to do this, but you've done a perfect job already. I'm still seeing the same issue, exactly as described, even after the latest update. Acrobat invariably crashes while trying to bring up a preflight profile.
