Microcontroller not detecting in IPE and Pickit3

Hi, I have bought PIC32MZ2048EFM064 IC and Adaptor and made circuit in General Purpose board. 
I have made following connections:
1) MCLR  - pin 9
2) VDD    - pin 26 (vdd)
3) GND   - pin 25 (vss)
4) PGD   - pin 18
5) PGC   - pin 17
 
And Microcontroller is not detecting in MPLAB X IPE as well as in PICKIT3. I don't know whether I missed something or controller gone.
And one more problem is I have installed Pickit3 OS from its programmer software Now I can't use MPLAB X IPE
Please Somebody help  me.
 
Thanks in Advance

    3) GND   - pin 25 (vss)

    You appear to be saying that you only connected the programmer to a single set of pwer pins on your PIC.
    That will not work.
    You must connect to ALL the VSS and VDD and AVSS and AVDD pins on the device.
    Examine "FIGURE 2-1:RECOMMENDED MINIMUM CONNECTION" in the datasheet. That also applies when programming, except you don't need the components on MCLR.

    On some PIC's there are alternatives to pgd and pgc
    Some have pgd2 etc
    These need setting up in the config.

    Thank you for the valuable guide.
    As I checked with multimeter all vss and vdd are connected internally. except avdd. 
    And I'm thinking of using one 1uF capacitor in my new circuit instead of using 0.1uF in each vdd and vss (as in datasheet). is that fine?

    Bad test. That only shows there is some DC connection. Ignore the recommendations at your peril.

     And I'm thinking of using one 1uF capacitor in my new circuit instead of using 0.1uF in each vdd and vss (as in datasheet). is that fine? 

    No.
    Experienced engineers don't make these recommendations just to make your life harder. I guess you are very inexperienced at high frequency design principals.

    Hi,
    Make sure to connect AVdd. It cannot be left open...
    It must be : 
    Greater of VDD – 0.3 or 2.1V   <= AVdd <= Lesser of VDD + 0.3 or 3.6V
    (see figure 2-1 as recommended above)
    Regards

    For support make sure to check first here : http://microchipdeveloper.com
    There are hundreds of PIC, AVR, SAM...which one do YOU use ?

    Have you checked for shorts between pins on your adapter board? Perhaps you have shorted some critical pins.

    I recently soldered a chip to a very similar adapter board, and even with 20 years soldering experience under my belt, 0.5mm pitch was not exactly trivial to solder without bridging any of the pins.
     
    Its impossible to see any detail in the photos you provided, so its hard to make further recommendations on what might be wrong.

    Dear toms,
    There is no shorts in between pins( I checked continuity of all 64pins) and IC soldered by a professional solderer. 
     
    I think I have problem in pickit3. It is not detecting my other 8bit controllers also. 
    I'm having cloned/duplicate Pickit3. I wanted to buy genuine one. But I can't identify the which is genuine or cloned. Please someone tell me where can I buy a genuine Pickit3 (In India or deliverable to India)

    Try buying direct from Microchips web store. You probably cant do better than buying direct from the manufacturer.

    Otherwise, do you have access to suppliers like RS, Mouser, Digikey, Farnell etc in India? There must surely be authorised distributors of Microchip products around (you may be able to find them on Microchips website), or perhaps a simple search. Just avoid the typical sources of fake or counterfeit products like ebay, Aliexpress and the likes unless buying from one of those distributors.

    Microchipdirect do not stock the PK3 any more, only the PK4.
    They are out of stock of the PK4 until April-22 :(

    The SNAP Programmer should also work.

    The PICkit3 on the picture attached to the first post looks genuine.

    Snap is a great cheap fast programmer.
    However, it doesn't supply power to the PIC.

    Hi,
    I know this is irrelevant but could somebody please tell me how to make a post?

    Assuming youve seen the button at the top of the forum. But otherwise you just have to be stupidly careful about what goes into your post, because often times trivial things will cause the forum to error out when you try to post.

    WooHoo.
    Finally Controller detected. Problem was simple. Controller should be powered up using other power supply. Pickit3 is not supplying power to controller.

    Indeed. The programmer defaults to not supplying power.
    It can, but you have to tell it to in the settings.
