Hi all,

I run IC-Prog on my one system and it works ok but when I run it on my laptop it shows an error window with title "Privileged Instruction" as shown in attachment. Is there any solution???

Download the attachment files, it contains the ICProg 1.5D and the Windows NT/2000 Driver.

Uncompress the ICProg and the driver in the same folder

In ICProg do this:

Settings --> Options -> Misc ; here you must mark "Enable NT/2000/XP Driver", after this accept all and restart ICProg.

I hope that this solve your problem.

Thank you dennis78. It helped me to work. Cheesy

Now the programmer on desktop system works OK and LED lights up when programming voltage (Which are 13V) applied and it is OK. But with my laptop LED does not lights up but it do program and verify .hex file. But PIC does not work as programmed. I measured VPP which are around 11-12V. Is there any way to increase VPP little bit. Please guide me if possible.

the serial/com port of the laptop today do not produce 13V, so maybe you could use pickit 2 or any programmer that uses USB for the interface, because usb produces 5 volts and laptop do provide it..

Use only your desktop pc rather than your laptop for burning the program to your microcontroller...

So if I make dc to dc converter for 13V from USB 5V then how much maximum safely current I can draw from USB?

USB supply can provide current up to 500mA.  It's much more than you need.

Separate the power supply for the programmer, just connect the transmit and receive port of the com port and include the separate power supply..

if it has a separate power supply, it will be able to supply the 13V for the microcontroller to be burn..
