Hi jiri_kral,
thank you for responding and looking into the issue. Here are some additional information so we can rule out potential causes.
1. I checked the integrity of the downloaded installer and it's correct.
lovro.jakic@ra-b203-ltu:~/Downloads$ md5sum S32DS.3.5_b220726_linux.x86_64.bin
65e7ede55835608c44731a1eaaad60a2 S32DS.3.5_b220726_linux.x86_64.bin

2. FNPLicensingService is successfully installed and active. "fnp_install.log" is in the attachments.
lovro.jakic@ra-b203-ltu:/usr/local/share/FNP/service64/11.18.2$ ./FNPLicensingService -r
Licensing Service daemon already active
lovro.jakic@ra-b203-ltu:/usr/local/share/FNP/service64/11.18.2$ ./FNPLicensingService -s
11.18.2.0:x86_64:19862:0
3. There are no other errors in logs, except for that java one in the previous response, but regardless, I will attach the ones that I found "e10144dd18dac94b818.details" and "lax-8586466944735677875-err.tmp".
4. I checked the shared libraries required by the "libcll_app_libFNP.so" which failed in that Java log and everything looks fine to me.
