I am restoring a legacy Precision Flight Controls Cirrus II simulator running Windows XP SP3 32-bit and Microsoft Flight Simulator X.

I am trying to locate an older XP-compatible copy of FSUIPC4 v4.957b, or another confirmed pre-4.96 version that works with XP SP3 and FSX.

The current FSUIPC4 releases no longer support Windows XP. A recent FSUIPC support discussion confirmed that 4.957b has been successfully installed and used on XP SP3 32-bit with FSX, but the current maintainer no longer has the older installer available.

If anyone has the original FSUIPC4 4.957b installer/package from a legitimate archive and would be willing to share it, I would greatly appreciate it.

The simulator uses a serial PFC Cirrus II console on COM1. I already have the current official PFC DLL package; the missing piece is the XP-compatible FSUIPC4 version.

I am specifically looking for an original, unmodified installer/package — not a cracked or altered copy.

thank you very much

I just sent you one in an email. I used it on my WinXP computer running FSX Standard Edition in 2018.

I used my AVSIM email account!

It failed trying to send using my AVSIM account so I zipped the file and tried another email.

I just have to say, that is a neat idea for a project. Good luck to you.
