Writing an array of custom objects to CSV

Question

I am brand new to PS. I have been reading many, many forums and am stuck on something I think you all will find very easy.
Essentially all I want to do is use the test-path method to determine if a file and track yes or no. Repeat for several products. And finally export to a CSV.  So far I have cobbled together the If statement that will return a Yes Or No with the product name. 
Able to put it into an array of custom objects so I can export-csv without just getting the just the name lengths.  The problem is that I only get the last value of the custom objects over and over again.  Here's my simple code:
$hostname = hostname
$Products = @()
$myobj = "" | select COTS_Product, PassFail
If(test-Path -Path C:\"Program Files"\Java\jre7\THIRDPARTYLICENSEREADME.txt)
$myobj.COTS_Product = "JRE 7 on Host?"
$myobj.PassFail = "YES"
$Products += $myobj
else
$myobj.COTS_Product = "JRE 7 on Host?"
$myobj.PassFail = "NO"
$Products += $myobj
##Product 2
If(test-Path -Path H:\Smileys\6.gif)
$myobj.COTS_Product = "Smileys 6 on Host?"
$myobj.PassFail = "YES"
$Products += $myobj
else
$myobj.COTS_Product = "Smileys 6 on Host?"
$myobj.PassFail = "NO"
$Products += $myobj
$Products | Export-Csv H:\$hostname.csv -NoTypeInformation
Here's my output:
COTS_Product
PassFail
Smileys 6 on Host?
YES
Smileys 6 on Host?
YES
SHould Be:
COTS_Product
PassFail
JRE 7 on Host?
YES
Smileys 6 on Host?
YES
Please Help.

You have been  reading a lot of very old and very faulty misleading forums.  Start by actually sitting downa nd trying to learnPowerSHell.  You cannot guess your way through any relatively sophisticated technology.
Here is a little example of a way to do this in PowerShell.
function Test-Product{
Param(
$product,
$path
New-Object PsObject -Property @{
COTS_Product=$product
PassFail=Test-Path $path
$test_products=@{
'JRE 7'='C:\Program Files\Java\jre7\THIRDPARTYLICENSEREADME.txt'
'JSmileys 6'='h:\Smileys\6.gif'
$products=foreach($key in $test_products.keys){
Test-Product $key $test_products[$key]
$Products | Export-Csv H:\$hostname.csv -NoTypeInformation
This can be expanded in any way needed without issues.  It uses the design of PowerShell to set up the objects so they are manageable.  Until you learn about objects and formal programming logic and some elements of design you will have some difficulty
in figuring out how to do these things.  Once you learn the basics they will seem very simple.  You cannot learn the basics from reading forum posts.
