Error: "A managed exception was caught..." opening User-Maintained tax tables
Description
Cause
  • The TAXTABLE.DAT file contained in your individual company directory has become damaged.
  • This happens when a tax update goes to a specific company folder instead of the data path.
  • User Account Control can block access to the network data location.
Resolution
CAUTION: Use caution when working with the below product functionality. Always create a backup of your data before proceeding with advanced solutions. If necessary, seek the assistance of a qualified Sage business partner, network administrator, or Sage customer support analyst.

Extract TAXTABLE.DAT file from a Backup (.PTB) File

  1. Make a backup of your company.
  2. Find your company location and make a note of the directory.
  3. Close Sage 50 on all computers.
  4. Open File Explorer and browse to the company directory noted in step 2.
  5. Right-click TAXTABLE.DAT and select Rename.
  6. Rename the file to OLDTAXTABLE.DAT.
  7. Find a backup file (.PTB) created before the error occurring.
  8. Right-click and Copy the file. Then go to the Desktop.
  9. Right-click a blank area of the Desktop and select Paste.
  10. Right-click the backup file and select Rename. Change the PTB extension to ZIP.
  11. Right-click the .ZIP file and choose Extract All.
  12. Open the extracted folder, right-click TAXTABLE.DAT, and select Copy.
