Hi there I've a Nokia E7 running Symbian Belle FP2 Refresh & when I'm installing the 'dosbox.sisx' file I'm getting a Certificate Error "Certificate Expired" & the installation terminates without starting at all. Please help, I've checked the Settings in the Installation Settings and there were no restrictions upon any installation method(s). thanks in advance.
Set your data to some time in 2010, install dosbox.sis, set the date back to the original value. Worked for me.
