I can see you’ve done your due diligence trying to get this resolved already, bgarrett012.

I appreciate you for performing some solutions to get this sorted out. This occurs when QuickBooks can’t access the fiblueprint.xml file due to user permission restrictions. It'll usually happen when you use QuickBooks in a hosted, terminal service, or Citrix environment. To fix this, let's start by ensuring you have the appropriate user permissions to C:\ProgramData. Here's how:

1. Find and open your QuickBooks folder in C:\ProgramData.
2. Find and double-click on the fiblueprint.xml file.
3. If the file opens, close it and restart QuickBooks.

Once done, try working on your bank feeds again. If you can’t, you need to grant full access to your profile. 

1. Right-click anywhere in the folder.
2. Tap Properties.
3. Go to the Security tab.
4. Choose Edit.
5. In the “Group or user names” section, select Everyone.
6. In the “Permissions for Everyone” section, select Full control.
7. Close the Edit and Properties windows.
8. Restart your computer, then open QuickBooks. Retry working on your bank feeds.

If unable to set the permissions, I recommend working with your hosting provider or an IT professional to update it. If the same thing happens after following the steps above, continue with Solution 2: Fix Microsoft .NET Framework, MSXML, and C++ in this article: Fix System Exception errors.
