Resolving EasyACCT error: This Company has been converted to a later version / Application mismatch error

When opening a company I receive "This company has been converted to a later version" or "Application Version Mismatch: The selected company is on a more recent application version. Click on update to upgrade your application and then retry opening the company file."

1. These messages occur in network environments when a company has been opened on a different computer with a more recent program version installed.
   • A user on a computer with an older version will encounter this error message, as a company cannot be opened in an earlier version once accessed in a newer version.
2. This will also occur when a new computer is placed in service, and an earlier version of the program year is installed on the new machine without all the updates.

In either case, the program will need to be updated to the same version as the data was last accessed.

EasyACCT for tax year 2024 and earlier was retired on March 6, 2026. This change is part of an intentional upgrade as we modernize the system. These updates are part of our ongoing work to improve performance in tax year 2025 and future releases, while also meeting evolving security standards and supporting future enhancements. Downloads for tax year 2024 and earlier will be disabled. Any references to Prior Year in this article will not apply until the 2026 program is released and 2025 program becomes a prior year.

How can I fix it?

Information Return System:

• In the Information Return System, if a new computer requires a prior year IRS program to be installed, there are several ways to accomplish it.
  1. If the program year is 2025 to the current year, the updated programs can be installed from the MyAccount download service.
  2. If you still have possession of the old computer, you can use the Network folder from the old computer to install it to the new computer.
  3. If the download is not on My Account, call Technical Support and request a download link.

EasyACCT:

• Install the latest update, either by selecting the Update button or downloading it from My Account online.

If you do not have the current year program version:

• Delete the Company.### file and Create a New Company with the same ID and same information.
  1. Right click on the Company from the Company Selection screen and Select Properties.
  2. Print the Properties for re-entering the information in a New Company ID.
  3. Do a Windows Search for Company.### where ### is the 3 digit Company ID.
  4. Right Click and rename the file Companyold.###.
  5. Create the New Company using the Company Wizard and use the Print out from Step 2 to make sure the information is identical.
  6. This will allow the older machine to open the same company file that was converted to the newer version.
• If the problem persists, restore the automatic backup.
