๐งน Part 3: Full Clean Reinstall (Advanced)
โ ๏ธ Use this method only if the normal reinstall (Part 2) doesn't fix your issue. This completely removes all cached module files.
Step 1: Uninstall the Module First
Follow the steps in Part 1 above to uninstall the module normally:
Tools → Utilities/Setup Assistant → Tools → Uninstall Modules
Step 2: Navigate to the MAILBOX Folder
- Open File Explorer (Windows key + E)
- Navigate to your Sure-Fire installation folder:
C:\UTSXX\MAILBOX
Where XX = last 2 digits of the tax year
๐ Example Paths:
• C:\UTS25\MAILBOX = Tax Year 2025
• C:\UTS24\MAILBOX = Tax Year 2024
• C:\UTS23\MAILBOX = Tax Year 2023
Step 3: Delete STU Files
- Inside the MAILBOX folder, scroll to the bottom (files are in alphabetical order)
- Look for any files that start with STU
- Delete all files beginning with "STU"
๐ What STU files look like:
• STUIUS01.ZIP, STUIUS02.ZIP (Federal - US)
• STUICA01.ZIP (California)
• STUINY01.ZIP (New York)
• STUITX01.ZIP (Texas)
• etc.
Step 4: Reinstall the Module
- Go back to Sure-Fire Tax Software
- Go to Communications → Get Module Updates
- Wait for the fresh download and installation
โ Done! You now have a completely fresh installation of the module with no cached data.
