Adobe Creative Cloud installation failed with Error 1603

Fatal error during installation. (Error code: 1603)

Error 1603 is a generic MSI-level fatal installation error that is computer-specific. It does not point to a single root cause — the actual cause must be identified by reviewing installation logs. Common underlying issues include insufficient folder permissions, running background processes, and startup items interfering with the installer.

Observed message

Fatal error during installation. (Error code: 1603)

Why it happens

Insufficient permissions on a folder required by the MSI installer (e.g., the Windows Color folder).
Conflicting background processes or startup items interfering with the installation.
Leftover files from a previous installation blocking the current install.
The installer requires a system restart that has not yet occurred.

How to fix it

Review the PDApp.log or Install.log files to identify the specific cause behind the 1603 error.
Disable startup items and non-essential background services before retrying the installation.
Correct permissions on any folder identified in the log (e.g., granting Administrators Full Control on C:\Windows\System32\spool\drivers\color).
Run the Adobe Creative Cloud Cleaner Tool to remove residual files from prior installs.
Restart the computer and attempt the installation again before other applications start.
