Runtime Error R6025 – Pure Virtual Function Call is a Microsoft Visual C++ runtime error that can pop up in QuickBooks when the program unexpectedly calls a “pure virtual function” in an invalid way. In simpler terms, QuickBooks tried to access something it shouldn’t have—usually because of a glitch, damaged file, or a conflict with another program.
Common Causes:
- Corrupted or missing QuickBooks components.
- Issues with the Microsoft Visual C++ Redistributable package.
- Background apps (like antivirus) interfering with QuickBooks.
- Damaged QuickBooks company files or program files.
How to Fix Runtime Error R6025 in QuickBooks:
1. Reboot Your System
- This clears out temporary memory glitches that might be triggering the error.
2. Use QuickBooks Tool Hub
- Download from Intuit’s official site.
- Open it and go to Program Problems > Quick Fix my Program.
3. Repair Microsoft Visual C++
- Go to Control Panel > Programs > Programs and Features.
- Find Microsoft Visual C++ Redistributable (look for the year QuickBooks needs, like 2015 or 2013).
- Right-click > Change > Select Repair.
- Restart after repairing.
4. Update QuickBooks and Windows
- Make sure QuickBooks and Windows are fully updated to the latest versions.
5. Reinstall Microsoft Visual C++ (if repair fails)
- Uninstall the version causing issues.
- Re-download from Microsoft’s site and reinstall.
6. Clean Install QuickBooks (if the problem persists)
- Use QuickBooks Clean Install Tool to fully uninstall and reinstall QuickBooks.
Pro Tip:
If the error happens while doing something specific (like opening a report or printing), note the action—it can help pinpoint corrupted templates or features.

=======================
The QuickBooks validation code (aka product activation info) is encrypted and stored in the Windows Registry after you successfully activate the software. It ensures QuickBooks knows the product is licensed for that system.
However, Intuit does not allow or recommend manually retrieving or editing the validation code due to encryption and licensing security.
Location in the Registry (for reference only):
HKEY_LOCAL_MACHINE\SOFTWARE\Intuit\QuickBooks\<version>\Registration
- Replace <version> with the version year, like 2023 or 2024.
- The entries here typically include:
- LicenseNumber
- ProductNumber
- QBREGISTRATION.dat file references
- Encrypted Entitlement values
Important:
- These values are encrypted, so you can’t extract the actual validation code directly.
- Modifying these keys can corrupt your QuickBooks installation or break the licensing.
- Always back up your registry before making any changes.
Legit Ways to Retrieve Your License/Validation Info:
- Check your confirmation email from Intuit (if you purchased online).
- Log in to your Intuit account
- Look inside QuickBooks:
- Open QuickBooks.
- Press F2 or Ctrl + 1 → You'll see your License Number and Product Number in the Product Information window.
Let me know if you want a small PowerShell or script snippet to read-only pull license keys from the registry for IT auditing—just for info, not activation bypassing.
