I am trying to create a table with specific software I have on my computer and their Version.
I would like if the Software doesn't exit to put software name under the header DisplayName and under the header DisplayVersion to put Not Installed.
It works fine if the software exists but if it doesn't it doesn't put the name under the header and put a blank line on the excel file.
example what I am taking now is :
DisplayVersion DisplayName
Gimp 2.8.22
7-Zip 18.01
Notepad++ 7.5.8
What i Want
DisplayVersion DisplayName
Gimp 2.8.22
7-Zip 18.01
Adobe Acrobat Not Installed
Notepad++ 7.5.8
any suggestions ?

Give this one a try in your else statement:
$array += #(1 | Select-Object #{Name="DisplayName";Expression={$program}},#{Name="DisplayVersion";Expression={'not installed'}})
With this, you create a custom object and add it to your array.
Hope it helps.
