Hi sozbayraktar It looks like a problem with the update. Could you please unistall your current version and install the version dowloadable at this [link](https://cdn.ikalogic.com/dist/scanastudio/package/scanastudio_setup.exe)

Dear Nicolas, First of all, let me express my satisfaction with fast responses of Ikalogic team. Actually I have known Ibrahim Kamal since more than 10 years, when I was using his small SW tools to program my Atmel 89C59 8 bit microcontrollers (my SIEMENS days). Coming to this issue: Uninstalling and re-installing didn't solve the problem. I found a round about for this by down loading the scripts from Github and pasting them into Scana Studio scripts folder manually. Now it works fine. Solved until next update requirement. Thanks again for your attention. Kind regards, Selcuk Ozbayraktar

I had the similar issue under Ubuntu 20.04; In my case the root cause was missing Qt dependency on libssl1.0; libss1.1 is installed by default starting from Ubuntu 18.04; In order to fix the issue I downloaded and installed [libssl1.0](de.archive.ubuntu.com/ubuntu/pool/main/o/openssl1.0/libssl1.0.0_1.0.2n-1ubuntu5.4_amd64.deb) manually: *The missing library should be either packaged together with ScanaStudio or dependency must be resolved in another way.*

Thanks same issue on Fedora 33, solution was to install compat-openssl10. Note I also had to download and install libftd2xx.so from ftdichip.com/drivers/d2xx-drivers/ into /usr/lib64/ in order to get it to start

Hello, I’ve had the same problem on my Dell Latitude (Windows 10 OS), with ScanaStudio 4.0.17, and I’ve found a solution. If you still have an Internet connection problem with your version of ScanaStudio it is likely that the Microsoft Visual C ++ 2015-2019 Redistributable (x64) library is missing. You can download and install it from: https://visualstudio.microsoft.com/fr/downloads/ Then you go to the "Autres outils et infrastructures" tab where you will choose “Microsoft Visual C++ Redistributable pour Visual Studio 2019”. After installing these library the connection, when launching ScanaStudio, should be operational. Have a nice day.

Thank you @alain_ma for sharing that.

Recently I faced the same issue with Fedora 34 even if comapt-openssl10 is installed. One need to provide the library path explicitly to _libftd2xx.so_ found in */usr/local/lib* and create the proper links to _libssl_ and _libcrypto_ accordingly. `cd ~/Ikalogic/ScanaStudio mkdir lib64 ln -s /usr/lib64/libssl.so.10 lib64/libssl.so.1.0.0 ln -s /usr/lib64/libcrypto.so.10 lib64/libcrypto.so.1.0.0 LD_LIBRARY_PATH=$PWD/lib64:/usr/local/lib:$LD_LIBRARY_PATH ~/Ikalogic/ScanaStudio/ScanaStudio`

Hi, I faced the same issue on my debian 11. In my case the solution is to download the stretch package of libssl1.0 (https://packages.debian.org/stretch/amd64/libssl1.0.2/download), and unpack the content of /usr/lib/x86_64-linux-gnu into the ~/Ikalogic/ScanaStudio/lib Restart of Scanastudio and everything is fine now :) We'd all appreciate if you could update your installer to include by default this lib. Thanks !

Thank you @rikagam for that info, i'm forwarding that to Nicolas for future updates.
