We appreciate you for reiterating your QuickBooks product, Credit1. Let's work together to fix the error you encountered when opening QuickBooks Desktop (QBDT) so you can resume your business activities.
Error message 6150 indicates a potential data integrity issue. This can usually be caused by internal (within QuickBooks) or external (file location) factors. To get rid of it, we'll have to install the most recent version (1.6.0.3) of QuickBooks Tool Hub and then run the File Doctor utility.
For the best experience, we recommend using this tool on Windows 10, 64-bit. Then, follow the steps below to run QuickBooks File Doctor:
- Go to Company File Issues.
- Select Run QuickBooks File Doctor.
- Select your company file from the drop-down menu.
- Choose Check your file, then tap Continue.
- Enter your admin password and click Next.
Once finished, open your QuickBooks company file again.
