I'm receiving the following error when I open QtFuzzyLite

Interesting.

Seems to be an issue with OpenSSL.

Was it working before?
Or is this the first time you open it?
Is it registered or were you trying the demo?
If registered, can you forward me the registration email at jcrada@fuzzylite.com to try it myself?

Thanks!

• I've opened it before but it has been several years since I tried to use the application.
• I downloaded the latest binary from your website and got the same error.
• I forwarded you the email from xzy3@cdc.gov

[jcrada]

Thanks!
I asked Google Gemini and offered this solution:

1. Disable the Version Check / Network Access
   QtFuzzyLite may crash because it attempts to connect to the internet to check for updates. Since the crash happens in QNetworkAccessManager, disabling this check can bypass the faulty SSL initialization.

Locate your configuration file (usually ~/.config/fuzzylite/QtFuzzyLite.conf).

Look for checkForUpdates and change it to checkForUpdates=false

Would you mind trying that?

[jcrada]

If that doesn't work, the next suggestion is:

3. Install OpenSSL 1.0 Compatibility Libraries
   RHEL 8 uses OpenSSL 1.1 by default, but QtFuzzyLite 6.0 is likely linked against an older version. You may need to install the compatibility layer:

sudo dnf install compat-openssl10

[xzy3-cdc]

• That config file didn't exist. I created it but I'm not sure I formatted the file correctly. Same result.
• that library was already installed when I went to look for it.

[jcrada]

I have not used Red Hat, so I don't know where the configuration file lives.

I think the best bet would be installing VirtualBox and within installing Linux Mint or Ubuntu (maybe older versions), and use QtFuzzyLite there.

QtFuzzyLite still runs fine in Mac with the latest OS. That's as much as I can test against at the moment.

[xzy3-cdc]

I tested it on my Ubuntu box and it works. So it seems to be specific to the redhat environment.
