Let's use File Doctor to fix company issues in QuickBooks Desktop. To proceed, we need to download and install QuickBooks Tool Hub. 

Here's how:

Then run QuickBooks File Doctor:

2. Select Run QuickBooks File Doctor. It can take up to one minute for the file doctor to open. 
   
   
   
3. In QuickBooks File Doctor, choose your company file from the drop-down menu. 
4. Click Check your file (middle option only) and then select Continue.
5. Enter your QuickBooks admin password and then select Next.

The scan time depends on your file size. In most cases, it can take up to 5 minutes. Once the scan finishes, open QuickBooks and your company file.
