OrCAD unable to find netlist file.

Hi there,

I'm quite new to this OrCAD Capture software, using a 9.1 edition.
I'm actually patching up a circuit for a charge controller according to this link: https://www.mdpub.com/555Controller/images/555ChargeController.jpg
This is my schematic diagram.
https://obrazki.elektroda.pl/6855597400_1372616126.png
But when I click on Run simulation, it shows the message in the output file "unable to find netlist file....simulation aborted"
I did some searching for any similar problem and below are the possible solutions:

1) Generating a layout netlist
- Bring up the project window.
- Select the schematic that is being worked with.
- Under "Tools" menu, select "Create Netlist" (for mine, I need to go under "PSpice" menu)
- Select "layout" on the top tabs
- The defaults should be correct for the file name to create the file dimensions. Press ok to create the netlist.

[While doing this above steps, a window pop out instead after step 3, displaying the message "Simulation aborted because there are errors during netlisting. Please refer to session log".
The session log displayed "Creating PSpice Netlist Writing PSpice Flat Netlist G:\MPSIP\PSPICE\ORCAD_DEMO\CAPTURE\1\CHARGE CONTROLLER-SCHEMATIC1.net
ERROR [NET0075] Unconnected pin, no FLOAT property or FLOAT = e U7 pin 'NO'

So I went to try how to correct the error with the below solution I found in the net]

2) SOLUTION from www.orcad.com
- In Capture, select the part.
- From the Edit menu, choose Part.
- Double-click the pin. The Pin Properties dialog blox appears.
- Click the user Properties button and make sure that there is a FLOAT property with the value UniqueNet listed. Add this property and value if it is missing. Click OK.
- From the File menu, choose close to save the instance. Click the update ALL button.

[After this, I went to run the simulation, but still theres is still the message "unable to find netlist file....simulation aborted."
But when I went to create and view the netlist, the session log displayed
"Creating PSpice Netlist
Writing PSpice Flat Netlist G:\MPSIP\PSPICE\ORCAD_DEMO\CAPTURE\1\CHARGE CONTROLLER-SCHEMATIC1.net
PSpice netlist generation complete" ]

Anyone can help me with this? I really have no idea why it does not run the simulation after all I had done. Thanks.

Before creating the Netlist you must first Run the DRC (Design Rule Check), I suppose there are some errors left unsolved that's hampering your netlist creation, address those errors and then create the netlist hopefully it will works as there is no rocket science in creating a netlist!!
