Thank you for clarifying your issue, @TG2b. 

I've already provided the possible reasons why you'll need to enter the administrator password when opening QuickBooks and how to fix it on this thread. But don't worry, I'll restate it for you if you missed looking at it.

Here are the possible reasons why you need to enter the administrator password to open QuickBooks Desktop:

• The file is saved in a protected location such as the root of C:// Drive or Program Files of a Windows Vista, 7, or 8.
• The file is located in a restricted location.
• Folder permissions are not set up properly.
• The folder where the company file is saved is damaged.

To resolve this, let's perform some various solutions. Firstly, let's start with running the QuickBooks File Doctor. This way, it'll help us resolve common errors. 

Once done, you'll have to set QuickBooks to run as administrator. Here's how:

1. Close QuickBooks Desktop.
2. Right-click the QuickBooks Desktop icon, then select Properties.
3. Under the Compatibility tab, choose Run this program as administrator.
4. Hit on Apply, then OK.

After that, let's move the company file to its default location.

1. Close QuickBooks Desktop.
2. Browse to the location of your company file.
3. Right-click the company file (.qbw), then click Copy
4. Browse to the default location, right-click and select Paste.Location:C://Users/Public/PublicDocuments/Intuit/QuickBooks/Company Files
5. Open the company file from the default location.

If the issue persists, I suggest performing Solutions 4 and 5 found in this article: You do not have sufficient permissions to the specified folder.

You may also want to know more about setting permissions in your company file. This article will guide you through the process: Set up a folder and Windows access permissions to share company files.

Come back to this post and let me know how it goes, @TG2b. I'll be around if you need further assistance.
