I assume you're referring to the ten year old posts at the start of this topic.
Yes, it's still possible to make PCBs at home yourself, but so long as you can wait a couple of weeks, there are very cheap prototyping services now that can make a small number of professional boards for something like US$5 total for five boards.

I have a new PicKit2 and am trying to use v8.92. When I use the project wizard to start a new project, I get the error message "Int_Vector can not fit the absolute section  Section 'Int_Vectorsrart=0x04  length=0x0000012. I'm using a 16F628A. There should be NO errors starting this new project yet I consistently get this error. I'm completely out of ideas how to fix this. I've tried everything I can possibly think of yet the error code persists. Apparrently it is a linker problem but I'm not even sure of this. I'm new to these forums and hope I've placed this in the right place. I've done assembly code but I can't get airborn till I can get this ProjectWizard thing figured out. I need some smart people with this. Can anyone help me? I'd be forever thankful. Sincerely Rob Thompson

0x0004 + 0x0000012 = 0x0016  Did you place anything there?

Are you deliberately using a very old MPLAB?
Yes, there are reasons to use an old one, just be sure you are doing it deliberately.

When I use the project wizard to start a new project, I get the error message "Int_Vector can not fit the absolute section  Section 'Int_Vectorsrart=0x04  length=0x0000012. I'm using a 16F628A. There should be NO errors starting this new project yet I consistently get this error.

How about showing us the code you tried to assemble. It's probably a simple problem, but we can't work blind.

Hi. I'm using V8.92 because the link came with the Cana Kit PicKit2. Is there a newer one and where would I
 get it? And also, I have no assembly code because I'm starting a brand new Project. The template and the linker
 are the two files necessary to make a new project with the Project Wizard (MPLAB). When I do the"Build All",
 that's when I get the error message. It says the linker failed. I'm a semi-newbie but I had a PickStart Plus for five
 years and never had a problem. I hope my questions aren't too far off base. Thanks for any help with this. I'm
 super pleased that anyone at all replied.   Rob

Should I try using MPLAB X IDE instead of MPLAB v8.92??
Any real harm?

You are pretty close to me in Catonsville. I often attend the free concerts at Lurman Theater, and I took machine shop classes at CCBC in 2014-2015.
 
If you plan to do serious development using PICs you might as well get used to MPLABX and XC8. Unless you have good reason to learn assembly, you may find C a lot easier. I have a PICkit2 and an ICD2 and I started out with a PICstart+, but I now use my PICkit3 exclusively. Your PK2 must be a clone - and the currently available tool is the PICkit4. Your tool may not be the problem, but it is good to use genuine Microchip parts in case you need support.
 
You are welcome to PM me if you want to discuss your projects on the phone or (eventually) in person.

The MPLAB project wizard literally just creates the project file. It does not include any source code into the project, unless you manually select a source file from somewhere.
That is why I asked to see what source you are using.
Did you add in some prepared file, or create something yourself?
 
OR, are you talking about some other "Project Wizard" altogether?
