MFA required for electronic filing

Effective May 3rd, the 2017 version of UltraTax CS requires multi-factor authentication (MFA) to transmit e-files from CS Connect. Find out more.

If UltraTax CS, Fixed Assets CS, or FileCabinet CS repeatedly warn that a desktop setup needs to be performed, even after following the prompts to run the desktop setup, try each of the following to resolve the issue. After each step, attempt to open the program.

Run the desktop setup as administrator

  1. Navigate to one of the following locations, depending on which program is prompting you to run the setup. In
    • UltraTax CS: WinCSI\UTYY\Desktop, where YY represents the year of UltraTax CS
    • Fixed Assets CS: WinCSI\DSW\Desktop
    • FileCabinet CS: WinCSI\CABINET\Desktop
  2. Right-click Setup.exe and choose Run as Administrator.

Rename the Prereqchk.dll file within the Desktop folder

  1. Navigate to one of the following locations, depending on which program is prompting you to run the setup.
    • UltraTax CS: WinCSI\UTYY\Desktop, where YY represents the year of UltraTax CS
    • Fixed Assets CS: WinCSI\DSW\Desktop
    • FileCabinet CS: WinCSI\CABINET\Desktop
  2. Right-click Prereqchk.dll and choose Rename.
  3. Add .old to the file name.

Uninstall and reinstall Microsoft Visual C++

  1. Find the version of C++ that the CS program you are having trouble with uses; refer to the "Versions of .NET Framework and C++ Used by CS Applications" section of the .NET Framework and Visual C++ Considerations for CS Professional Suite.
  2. Uninstall the version(s) of C++ that you found in step 1. Consult your IT professional for assistance, as C++ is a Microsoft component outside of the CS Professional Suite.
  3. Navigate to one of the following locations, depending on which program is prompting you to run the setup. In
    • UltraTax CS: WinCSI\UTYY\Desktop\vcredist_x86, where YY represents the year of UltraTax CS
    • Fixed Assets CS: WinCSI\DSW\Desktop\vcredist_x86
    • FileCabinet CS: WinCSI\CABINET\Desktop\vcredist_x86
  4. Open the folder that corresponds with the version of C++ you uninstalled. You need to repeat this step for each version of C++ affected.
  5. Double-click vcredist_x86.exe.
  6. Click Install.

  2. Look for the application's exe file. UtwYY.exe, where YY equals year of program, dsw.exe or fcab.exe
  3. Double click the exe.
  4. If the program opens now, right click the exe file, Send to>Desktop and you will end up with an icon on the desktop.
