ERROR 80070057

How to Fix QuickBooks Error 80070057 (Parameter Incorrect)

⏱ 10–15 minutes ● Easy difficulty Updated May 2026

What it means: QuickBooks cannot read the company file because Windows is passing incorrect parameters. This usually means the file was opened the wrong way, the file extension association is broken, or the file path contains special characters.

Before you start: Close QuickBooks on all computers. Make sure you know where your company file is stored. Do not rename the file until you have a backup.

Fix 1: Open the File from Inside QuickBooks

Do not double-click the .QBW file in File Explorer.

Open QuickBooks first to the "No Company Open" screen.

Click Open or restore an existing company.

Browse to your file and select it.

Opening from inside QuickBooks ensures the correct parameters are passed.

Fix 2: Check the File Extension

In File Explorer, make sure you can see file extensions.

Go to View → Show → File name extensions.

Your company file should end in .qbw.

If it ends in .qbb (backup) or .qbm (portable), you need to restore it first, not open it directly.

Fix 3: Move the File to a Simple Path

Long paths with special characters (#, %, &, @) can cause this error.

Copy your company file to a simple location like C:\QB\Company.qbw.

Try opening it from there.

If it works, the original path was the problem.

Fix 4: Run QuickBooks as Administrator

Right-click the QuickBooks icon and choose Run as administrator.

Try opening the file again.

If this fixes it, the issue is Windows UAC blocking file access.

Set QuickBooks to always run as admin: right-click icon → Properties → Compatibility → check "Run as administrator."

Frequently Asked Questions

Why does double-clicking the file cause this error?

When you double-click a .QBW file, Windows decides how to open it. If the file association is broken or points to the wrong QuickBooks version, it passes bad parameters. Always open QuickBooks first, then open the file from inside.

Can a damaged file cause 80070057?

Rarely. This error is almost always about how the file is being opened, not the file itself. If you can open other .QBW files but not this one, then the file may be damaged.

What if the error happens on a network file only?

The network path may be broken or the mapped drive letter changed. Browse to the file using the full UNC path (\\computer\share\file.qbw) instead of a mapped drive letter.
