Thus US versions of Keil do not come with dongles. For LPT based dongles you will need to get proper NT/2000 driver.&lt;br /&gt;

&lt;br /&gt;
You can work under Windows 2000 &lt;br /&gt;
with C51 v5.xx &lt;b&gt;only&lt;/b&gt; if you have non-protected (via hardware key on LPT) version.&lt;br /&gt;
I think, this is due to old Sentinel driver (snti386.dll) working under Windows NT don&amp;#39;t work under Windows 2000.&lt;br /&gt;
