CU*BASE Network and Hardware Specifications


These guidelines are designed for new credit unions who are converting to the CU*BASE platform with CU*Answers. The standards and guidelines outlined below should be used in the planning process for upgrading existing equipment, for the purchase of software and new equipment, and for preparation of the training site in anticipation of the conversion.


The guidelines are intended to help make the transition smoother and eliminate unnecessary complications and problems that come from untested or incompatible equipment and software. A successful conversion depends on many factors; network configuration, network security, and hardware compatibility are critical components in making sure your staff can reap the benefits of your CU*BASE investment from day one.

CU*Answers and CU*BASE Networking and Hardware minimum specifications are subject to periodic change. Please check with the Network Services team for the most current information prior to investment in new hardware, network-related equipment, or software.

Workstation Guidelines – Software

CU*BASE requires a Microsoft Windows Operating System to operate.

Each workstation also requires the following software:

  • Microsoft .NET Framework 4.5 (Provided by Microsoft)
  • Microsoft Visual C++ 2015 Redistributables (Provided by Microsoft)
  • Rocket LegaSuite Windows Client (Provided through CU*Answers)
  • IBM I Access Client Solutions (Provided through CU*Answers)
  • itextsharp.dll (Optional for PDF exports from the dashboard. Provided through CU*Answers)
  • Microsoft Excel 2013+ (Provided by Microsoft)


Windows 10 Professional 64-bit

* Considerations for choosing a 32-bit versus 64-bit operating system:

  1. CU*BASE is fully supported on both 32 and 64 bit Windows 7 operating systems.
  2. The main benefit of a 64-bit operating system is the ability to utilize more than 4GB of RAM. If you do not intend to order a workstation with over 4GB of RAM, then a 64-bit operating system would not be necessary.
  3. Some legacy devices and 3rd party applications may not function properly with a 64-bit operating systems. All currently supported CU*BASE peripherals have 64-bit driver support, however older, legacy peripherals may not. 3rd party applications should also be reviewed with the vendor to determine 64-bit compatibility.

Windows 7  will no longer supported by Microsoft as of January 1st, 2020 (see Microsoft product lifecycle). Any legacy hardware that was compatible with Windows 7 will not be supported, as well. Please contact CU*Answers Network Services if you would like a hardware proposal for new workstations or printers!

Please contact Network Services at 800-327-3478 (option 3) for any additional questions about choosing the right operating system.
