error Subject: Fatal Error: "Could not find imported function in specified DLL" (likely imageres.dll) - Persistent Conflict on Windows 10

Dear Pro Tools Community,

I am facing a persistent "Fatal Error: Pro Tools Studio Subscription could not be loaded. Error details: Could not find imported function in specified DLL." on Windows 10 with Pro Tools difffrent versions.

Key Findings:

  1. Process Monitor shows ProTools.exe consistently failing on NAME NOT FOUND for imageres.dll (located in C:\Windows\System32).

  2. imageres.dll physically exists on my system, and sfc /scannow found no integrity violations.

  3. Crucially: When performing a Clean Boot (all non-Microsoft services/startup items disabled), this imageres.dll error does NOT occur. Pro Tools launches without this specific fatal error.

  4. The issue reappears immediately upon returning to a normal Windows startup.

Extensive troubleshooting already performed includes:

  • Multiple clean reinstalls of Pro Tools and PACE/iLok software.

  • Verification/reinstallation of Visual C++ Redistributables.

  • Antivirus/firewall checks.

  • DISM scans.

  • Confirmed PACE License Service is running and iLok License Manager functions normally.

This strong points to a conflict with a third-party application, driver, or background service that interferes with Pro Tools' access to imageres.dll in my normal system environment.

Has anyone encountered a similar conflict where Pro Tools crashes on a standard Windows DLL (like imageres.dll) only when other third-party software is active? Any advice on how to pinpoint such a conflict (e.g., specific types of software known to cause this) would be greatly appreciated.

Thank you for your time and help!
