Updating Adobe Acrobat - Potential STATUS_HEAP_CORRUPTION ?

Relevant area(s)

WinGet CLI

Relevant command(s)

winget install

Brief description of your issue

I got an update for Adobe Acrobat, and ran the install command (which always worked), and got a weird error message which seem to indicate a HEAP corruption. If this is really the case, we may have a security here as well.

Steps to reproduce

# winget list --upgrade-available --include-unknown
Name                   Id                          Version      Available    Source

# winget install -e --id 'Adobe.Acrobat.Reader.64-bit'

Expected behavior

that install is successful.

Actual behavior

• Winget install command shows unknown error: 3221226356
• App installer itself doesn't complain, but log file shows trying to defrag a hard drive, but I don't have any HD's.
• running winget list --upgrade-available, no longer show Adobe.

Was the install successful or not?
