How to Fix Acrobat CS6 Installation Exit Code 6 and Error 1603
Question details
The user needs to resolve an installation failure when installing Adobe Acrobat Professional CS6.
- Product
- Adobe Acrobat Professional CS6
- Device & OS
- not provided
- Scenario
- Installing Adobe Acrobat Professional from the Creative Suite CS6 package.
- Observed behavior
- The installation fails with Exit Code 6 and MSI error 1603, accompanied by a message stating that the Data1.cab file is corrupt or cannot be used.
Verify that your computer has a stable internet connection to ensure large file downloads complete successfully, and temporarily disable your antivirus software to prevent interference during installation.
Re-download and Extract Installation Files
A corrupt Data1.cab file usually indicates an incomplete download or damaged installation media. Re-downloading the files from a reliable source is the most effective fix.
When the installer payload reports a 1603 error alongside a corrupted cabinet (CAB) file, it means the extraction process cannot verify the integrity of the setup files. Running the installer from a local drive rather than a network or external drive can also prevent this.
Navigate to the official software portal and download the Creative Suite CS6 installation package again to ensure you have an uncorrupted copy.
Save the downloaded setup files directly to your local hard drive, such as your Desktop or Downloads folder.
If the download is a ZIP or compressed archive, right-click the file and select 'Extract All' to completely unpack the contents into a new folder.
Right-click the primary setup executable (usually setup.exe) in the extracted folder and select 'Run as administrator' to start the installation with elevated privileges.
Review Official Exit Code 6 Logs
If re-downloading the package does not resolve the issue, investigating the installation logs can pinpoint specific file conflicts causing Exit Code 6.

Frequently Asked Questions
What does MSI error 1603 mean during software installation?
MSI error 1603 is a generic Windows Installer error meaning 'Fatal error during installation'. It usually occurs when the system lacks proper administrative permissions, the installation package is corrupted, or existing software is conflicting with the setup.
Why is the Data1.cab file showing as corrupt when I try to install?
The Data1.cab file contains essential compressed data for the software. If it is corrupt, it means the file was not fully downloaded, your internet connection was interrupted, or the physical installation disc has scratches or damage.
How can I safely get support for persistent installation errors?
Always rely on official support channels through the software manufacturer's website. Be cautious on public forums; never post your product keys publicly or provide them to individuals who send private messages claiming to be support agents.
