Hi Frank,
Sorry for the difficulties here. Programs should prevent these sorts of issues. So let's see if we can work out what is causing the problem and fix it.
In version 1.07 and version 1.08 some of the settings were stored in the install folder. Specifically settings tied to each spacecraft such as the downlink frequency. If you changed that value in the GUI then it saved the new value back into the install folder. That appears to be working fine for you.
In 1.08 and 1.09 no settings are saved in the install folder. Instead they are saved into your data folder along with the telemetry that you download. This is the "user properties file" that it can not save. Why it can't save it is a good question.
So I need to know where you have saved the telemetry. This is the folder that is listed on File > Settings and is called the Log files directory. If 1.09 won't start then run 1.07 and let us know what that points to, unless you do something at each install to move the data around. We can then help you get this fixed and working.

Burns,
Thank you for the reply. I have foxtelem 1.07y, 1.08p, 1.08z3 and 1.09n3 installed on this computer each in its own directory. 1.07y and 1.08p launch and run properly. 1.08z3 and 1.09n3 each have the error message and do not start. All programs were downloaded and installed in the same manner. They are all on the same SSD and installed under a Windows administrator account. There is not a run directory in properties on any of the four versions. The computer only has one account/user which is the administrator. Properties on the folder do not list read only. At a loss as to why 2 older versions run and the last two versions do not run. Not being a Windows wizard I do not know where to go from here.

Frank,
I am not an expert on the internals of FoxTelem, but I have seen no
other answers, so I will chime in and ask whether you had FoxTelem installed on this same system earlier and whether you are starting it up specifying a data folder. (You do this by specifying a folder either on the command line if you start it that way, or in the shortcut properties). If you specify a data folder (directory), that has to be writable by you.
It says "run directory". That would be the directory where you actually
placed the folder that you downlinked, and which includes a "FoxTelem.jar" file. Is that writable, or did you somehow put it in a location that may be accessible to multiple users but not writable?

I installed FoxTelem 1.09 on a windows PC. When I launch the
application the error message “Could not write spacecraft user properties file. Check permission on run directory or on the file.” Don’t know how to fix this error message. Thanks for guidance.

A related question: When decoding the BPSK telemetry, what audio IF
range
can it be present in?
In the SatNOGS BPSK demodulator flowgraph, the audio output part of the flowgraph places the signal at a 12 kHz IF. This is necessary for 9k6
BPSK
transmissions, and we fixed it at 12 kHz even for 1200 baud BPSK to
ensure
the signal would remain within the 24 kHz passband (48 kHz sample rate) even if there was a bit of drift at either the ground-station or sat.
The
audio recordings are currently mainly used with the Funcube telemetry decoder, which is quite happy to decode 1200 baud BPSK at the 12 kHz
IF.
An example of such an audio recording, with a 1200 baud BPSK signal at
12
kHz IF is here:
https://ia803207.us.archive.org/32/items/satnogs-observation-2403591/satnogs... < https://ia803207.us.archive.org/32/items/satnogs-observation-2403591/satnogs...
Can FoxTelem be configured to accept BPSK at this IF? If so, then it
will
be possible to use any of the audio recordings from SatNOGS
observations,
even if a decoder is not developed in time.

Is there a link available to a description of the FOX-1E telemetry
format?
(modulation, framing, error correction, packet descriptions, etc...)
It would be nice to implement a decoder within SatNOGS, to enable the
300+
ground stations around the world to contribute telemetry...

For those of you with Fox-in-a-box telemetry stations (Fun Cube
Dongle in
a Raspberry Pi with FoxTelem software), FoxTelem 1.09 has been
successfully
tested on an FIAB.
It is easy to update your FIAB with the new FoxTelem version. Some
time
ago, I provided the instructions for upgrading to a new FoxTelem
release
at
http://burnsfisher.com/AMSAT/FoxInABox/Updating%20FoxTelem%20on%20your%20Fox... < http://burnsfisher.com/AMSAT/FoxInABox/Updating%20FoxTelem%20on%20your%20Fox...
and they will not have changed significantly other than the version numbers.
In any case, over the next few days, I will update and post the instructions as well as making the new version available on the FIAB
SD
cards sold in the AMSAT store and (a bit after that) on the free
download.
Thanks to Chris for a great new version!

This release provides several enhancements and needed changes for
RadFxSat,
also known as FOX-1E. This new spacecraft sends 1200bps BPSK telemetry in parallel with a linear transponder. Downloading telemetry and sending it to
the
server will assist AMSAT and the Radiation tolerance experiments from Vanderbilt
University.
You can download it here: http://amsat.us/FoxTelem/windows/FoxTelem_1.09n3_windows.zip <

http://amsat.us/FoxTelem/mac/FoxTelem_1.09n3_mac.tar.gz%3E
The following changes are in 1.09 (from 1.08):
- Performance improvements on the telemetry tabs. This uses less
CPU
than
1.08.
- Clearer display of historical records on the telemetry tabs for
RT,
MAX,
MIN and WOD.
- Bug fixes for Fox-1E decode and display of diagnostic tables,
Whole
Orbit
Data, formatting of telemetry
- Ignore extra commas in conversion curve comments
- Allow a single spacecraft to be downloaded from the Fox Server,
even
if
FoxTelem stores many spacecraft
- Latest Golf-T layouts for development
- BPSK CRC checksum calculation for GOLF-T
- Another new way to decode and display the mode
- More generic tab layouts to allow future expansion through soft
coding
- Throttle the DDE requests when decoder stopped
- Many other bug fixes
