SOLVED•by Intuit•26•Updated January 10, 2023

This error can manifest on an installation of ProSeries for a variety of reasons, such as:

  • The workstation installation cannot access the network drive.
  • A computer has more inbound connections than the Windows operating system allows.
  • A wireless connection has been disconnected.
  • The Run as Administrator checkbox is selected incorrectly.
  • Third-party software interfering with the ProSeries executable file.
