Data1.cab or a similarly named .CAB file.QuickBooks Error 1311 is an installation error that appears when QuickBooks Desktop cannot read a specific file needed to install or update the software. It also occasionally appears when exporting a report from the Financial Statement Designer to Excel.
You may see any of these variations of the error message, depending on your setup:
Error 1311: Source file not found: C:\Program Files (x86)\Intuit\QuickBooks 20XX\...\Data1.cabError 1311: Source file not found: D:\ZF561407.CABError 1311: Source file not found: \\SERVERNAME\QBInstall\Data1.cab (network installs)Notice that the file path tells you a lot — a C:\ or D:\ path points to a local/CD problem, while a \\servername\ path points to a network permissions problem. This distinction matters, because the fix is different for each. (See the diagnostic guide below.).
Before trying random fixes, identify your situation:
| Your Setup | Path in Error Message Looks Like | Likely Cause | Jump to Fix |
| Installing from CD | D:\…cab or E:\…cab | Damaged/dirty disc | Fix 1 |
| Installing from downloaded file | C:\Users\…\Downloads\…cab | Incomplete/corrupted download | Fix 1 + Fix 5 |
| Installing over a network share | \\servername\…cab | NTFS/SMB permission issue | Fix 6 |
| Export to Excel from FSD | N/A (happens during export, not install) | Microsoft Office compatibility issue | Fix 2 |
QuickBooks Error 1311 rarely has just one trigger — it usually stems from a problem with your installation source or the permissions guarding it. Below are the most common reasons this error appears, whether you’re installing from a CD, a downloaded file, or a shared network drive.
| Cause | Explanation |
| Damaged installation media | Scratched CD/DVD or corrupted download |
| Incompatible Microsoft Office version | Especially relevant for FSD-to-Excel exports |
| Restricted file/folder permissions | Missing admin rights or NTFS permission issues |
| Antivirus/firewall interference | Security software blocking installer access |
| Outdated Windows components | Missing updates or damaged system files |
| Network share misconfiguration | Incorrect SMB/NTFS permissions on shared installers |
Before you start troubleshooting, it helps to confirm you’re actually dealing with Error 1311 and not a related installation issue. Here are the telltale signs users typically encounter.
QuickBooks Error 1311 can be fixed by copying installation files to your hard drive, checking Microsoft Office compatibility, modifying CD-ROM access, using the command prompt, running the QuickBooks Install Diagnostic Tool, or resolving network and firewall permission issues.
For detailed steps, follow the solution guide below:

That strongly suggests a workstation problem. If the error were strictly server-related (like a locked file or a Database Server Manager failure), all users would typically be kicked out or unable to connect. When only one workstation sees the error, look closely at that specific machine’s configuration:
1. Is its Windows Firewall blocking the necessary QuickBooks ports (typically 8019 and others)?
2. Does it have the correct and most recent QuickBooks Database Server Manager client installed (even if it’s not hosting)?
3. Are the folder permissions (NTFS) on that workstation correctly set to allow full read/write access to the network share?
No, the core requirements for network sharing and permissions are the same across all QuickBooks Desktop versions (Pro, Premier, and Enterprise). All versions rely on standard Windows NTFS permissions and Windows Share permissions to ensure the necessary read/write access to the .QBW file and its companion lock files (.ND and .TLG}). The key requirement remains consistent: the user accessing the file—or the user account running the Database Server Manager—must have Full Control permissions on both the sharing tab and the security (NTFS) tab for the containing folder.
For shared installation sources, users should have at least Read & Execute access at both the folder AND file level. IT admins should confirm permissions aren’t being overridden by parent folders, security inheritance rules, or antivirus security policies—common causes of installation failures in Windows environments.
Yes. Windows Defender Firewall should allow QuickBooks services plus standard SMB/CIFS file-sharing ports (137–139, 445). In real offices, installations often fail when the firewall blocks workstation-to-server traffic. Whitelisting QuickBooks executables, Intuit services, and SMB ports ensures stable installation and file access.
Yes, you can fix QuickBooks Error 1311 by copying the installation files from the CD or external source to your hard drive. Once copied, run the setup from the hard drive instead of the external source, which can resolve the issue if the file access was problematic.
To prevent QuickBooks Error 1311 in the future, ensure that your installation media or files are not damaged by using only verified, intact sources. Always download QuickBooks from the official website. Additionally, run installations with administrator rights, keep your system updated, and regularly check for file corruption.
