I'll share some guidelines you can follow if you encounter an error when QuickBooks tries to access the company file.

The following may be the causes of the error:

1. One or more of the QuickBooks Desktop Support Files are damaged. These files are:

• The Transaction Log (TLG) file
• The Network Descriptor (ND) file
• The Data Source Name (DSN) file

2. The company file is damaged

3. Encryption software is installed

Here are some solutions you can follow.

Rename the QuickBooks support files:

1. Open the folder that contains your company file.
2. Look for files with the same name as your QuickBooks file but with extensions .tlg, .nd, or .dsn.
3. Right-click each file and select Rename. Add the word.OLD to each of them.
