Hi Ulf
?
3.54.164.0 is the File Version and has NO connection/relation to the program version which is 1.0.0.282.
?
282 is the Build number of the program.
?
What is the SDR H/W which you are using ?
?
Using Device Manager, Select Ports (COM & LPT) and check that COM1 is present.
?
The G8JCFCSDR has been installed thousands of times on everything from Windows XP to Windows 11, Raspberry Pi with Box86 + WINE, and on Linux x86/x64 with WINE, so I am very sure that we can get the G8JCFSDR working on your system.
?
BTW, you may prefer to get the very latest build, 284, from and the installer from which has improved error handling.
