HandiTax - The application has failed to start because its side-by-side configuration is incorrect in HandiTax

To fix the error, the application failed to start because the side-by-side configuration is incorrect in HandiTax, see the steps below.

  1. Close all HandiSoft programs before making any changes.

  2. Open File Explorer and navigate to the HSoft\Apps Folder.

  3. Rename the HtXX.exe.Config file (or for SQL: HtXXSql.exe.Config) to HtXX.exe.ConfigOLD.

    1. xx represents the year of HandiTax, e.g., HT22.exe.configOLD.

  4. Re-open HandiTax. This will generate a new config file, and the error should be resolved.

  5. Reset your ATO credentials after reopening HandiTax.

  6. Repeat these steps for each year of HandiTax where the issue occurs. For example, if the problem exists in the 2022 and 2023 versions, you must perform the fix for each year separately.
