I have also replaced old libeay32.dll with new one from 'bibuot' and now v5.107 running without errors :)
Copied this newer DLL into c:\windows\SysWOW64 (replaced the old DLL) v5.107 is running without errors but program starts up with important delay (1m30s) before program window is visible with the scan button. Scan works at normal speed. Old version of AdwCleaner was fast on initial star...
