Error 145: Troubleshooting ‘File Already Exists’ Conflicts

Adobe Error 145 occurs during an application installation or update when the Creative Cloud installer attempts to move or extract a file to a destination directory where a file or folder of the same name already exists and cannot be overwritten. This conflict is typically caused by orphaned files left behind by a previous failed installation, incomplete uninstalls, or active background processes holding locks on existing destination files.

Fast Fix

Open Task Manager (Windows) or Activity Monitor (macOS) and end all running Adobe processes. Open the installation log to find the conflicting file path specified in the error message, navigate to that directory, delete or rename the conflicting file or folder, and restart the installation from the Creative Cloud desktop app.

Quick Status Snapshot

• Severity: Medium (blocks installation or update; existing project files and user assets remain safe)
• Platforms: Windows 10, Windows 11, macOS
• Scope: Local target application folders (Program Files, Applications, or shared Adobe payload directories)
• Action Required: Identify and remove conflicting orphaned folders or terminate file-locking background processes

Diagnostic Path

Use the following checks to identify where the file collision is occurring:

1. Check the Installation Log for the Exact Path:
   • Locate the exact directory path throwing the collision. Open Install.log and search for Error 145 or fatal error 145. The log line will specify the source file and the destination path that is already occupied.
2. Determine if the Target Directory is Locked:
   • Try manually renaming the conflicting folder identified in the log. If the operating system displays a “File in Use” or “Action Cannot Be Completed” message, an active background process is locking the file. If background applications are interfering with file operations, consult Error 108: Conflict with Existing Software – How to Identify the Process.
3. Check User Account Permissions on the Directory:
   • If the file exists and you cannot delete or rename it even with no active processes running, your current user account may lack write/modify permissions on the parent directory. For permission-related extraction blocks, see Error 127: Extracting Files – Permission Denied on Program Files.

What Error 145 Means

During the final phase of an installation, the Creative Cloud engine extracts payload files into staging directories and then executes a batch move into the target installation directory (such as C:\Program Files\Adobe\[App Name] or /Applications/Adobe [App Name]).

If the destination path already contains an unexpected directory or file bearing the exact target name, the installer’s file-system operations are designed to halt rather than silently corrupt or overwrite unrecognized existing data. When the file-system API returns an error stating that the entity already exists, Creative Cloud aborts the operation and returns Error 145.

Common Causes

• Orphaned Folders from Incomplete Removals: An earlier version was uninstalled, but third-party plugins, custom scripts, or crash artifacts prevented the OS from deleting the main application folder.
• Corrupted Temporary Staging Folders: The installer’s temp directory retains an incomplete payload from an interrupted download or power failure.
• Conflicting Background Daemons: Adobe services (such as Adobe Desktop Service or CCXProcess) remain active in the background and maintain file handles on shared libraries in the destination folder.
• Stale Symlinks or Directory Junctions: A previous attempt to redirect installation directories across physical drives left a broken directory link. If file relocation failures occur between storage drives, review Error 146: Move File Failure – SSD vs HDD Path Issues.

Diagnostic Contrast

Error Code	Core Mechanism	Distinctive Behavior
Error 145	File/Folder Collision	Fails because a file or directory with the target name already exists at the destination path.
Error 146	File Move Failure	Fails because the installer cannot move a file from temp to destination due to drive paths or read-only locks.
Error 127	Directory Write Access	Fails during extraction due to explicit operating system permission denial on the target directory.

Resolution Steps

Step 1: Terminate All Active Adobe Processes

1. Windows: Press Ctrl + Shift + Esc to open Task Manager. Select and terminate all tasks matching:
   • Adobe Creative Cloud
   • Adobe Desktop Service
   • AdobeIPCBroker
   • CoreSync
   • CCXProcess
2. macOS: Open Activity Monitor, search for “Adobe”, select all related processes, and click the Force Quit (X) button.

Step 2: Locate and Rename the Conflicting Directory

1. Check the installation log file:
   • Windows: C:\Program Files (x86)\Common Files\Adobe\Installers\Install.log
   • macOS: /Library/Logs/Adobe/Installers/Install.log
2. Search the log for Error 145 to find the exact target path (for example, C:\Program Files\Adobe\Adobe Premiere Pro 2026).
3. Open File Explorer or Finder and navigate to the parent folder.
4. Rename the offending application folder by appending .old to the name (for example, Adobe Premiere Pro 2026.old).
5. Open the Creative Cloud desktop app and retry the installation.

Step 3: Clear Installer Temp Caches

If the conflict occurs inside a temporary download folder rather than the application path:

1. Windows: Press Win + R, type %localappdata%\Temp, and press Enter. Delete any folders prefixed with Adobe or {CreativeCloud}.
2. macOS: Open Finder, press Cmd + Shift + G, enter /tmp, and remove lingering Adobe installer payload folders.

Advanced / Professional Checks

• Run the Adobe Creative Cloud Cleaner Tool: If the installer continues to report collisions across multiple components, residual registry entries and unmanaged directories may be out of sync with Creative Cloud’s package database. Use the official cleanup utility to safely scrub orphaned deployment records. For step-by-step guidance, see Manual Uninstallation: How to Use the Adobe Cleaner Tool.
• Repair the Installer Bootstrap Engine: When internal package databases become corrupted and misidentify clean directories as existing collisions, reinstall the core deployment client. Consult Error 182: How to Repair the Adobe Installer Bootstrap for repair steps.

Hard Stops and Escalation

Stop manual file system modifications and escalate to your systems administrator if:

• The conflicting directories are locked by Windows System/TrustedInstaller permissions that cannot be modified with local administrator credentials.
• The target folders reside on an enterprise network share or redirected storage volume controlled by Group Policy, where file creation and replacement rules are enforced remotely.
