See my previous answer. BTW, what is size of the file you have downloaded?
I'm getting the same error message under Win XP. The message comes up right after selecting winscp375setup.exe. Also happens with winscp374setup.exe.
Any idea what's up?
Does it happen just after you run the setup or during the installation? If it happens just after you start it (no window appears yet), then the file is probably corrupted. Please check the files size and try to download the file again.
When running WinSCP350Setup.exe on Win2k, I receive error window with title "16 bit MS-DOS Subsystem" and message "The NTVDM CPU has encountered an illegal instruction. CS:10550 IP:0119 OP:65 63 74 20 61"
