Step #5: Check serial number expiration date

Put the following line to INI-file:

ExpDate=20000101

Format of the date is YYYYMMDD, it is important that you put date from the past. Run the application and you will see:

state = SERIAL_STATE_FLAG_DATE_EXPIRED
please register!

Let’s query some information before printing “pelase register”:

if (res)
{
	VMProtectSerialNumberData sd = {0};
	VMProtectGetSerialNumberData(&sd, sizeof(sd));
	printf("exp. date: y = %d, m = %d, d = %d\n", sd.dtExpire.wYear, sd.dtExpire.bMonth, sd.dtExpire.bDay);
	printf("please register!\n");
	return 0;
}

Run the application again and you will see why serial number is invalid:

state = SERIAL_STATE_FLAG_DATE_EXPIRED
exp. date: y = 2000, m = 1, d = 1
please register!

Remove the ExpDate=…. line from INI-file so we can check other limitations.
