Hello all,

I am packaging an application with the PowerShell Application Deployment Toolkit. During Post-Installation tasks, I would like to look and see if our AT&T VPN exists, and if so, remove it. I got this to work with a WMI query, but that is too slow, can cause issues, and forced an immediate reboot. My solution is to run AT&T's .exe with some silent switches. Here is my script:
Get-ChildItem -Path "C:\Program Files (x86)" | Where-Object {$_.FullName -Like "*at&t Global*"}
if ($_.FullName -Like "*AT&T Global*") {
Execute-Process -Path "$dirSupportFiles\agnc.exe" -Parameters "/S /v/qn /uninstall /norestart"
}
Else {
Out-Null
}

There are probably better ways to do this but I did not want it to throw errors. The deployment tool I am using is junk and there are no detection methods, just exit codes. Here is what I get when I run the script by itself:
Mode LastWriteTime Length Name
—- ————- —— —-
d—– 4/25/2018 9:28 AM AT&T Global Network Client

When I execute PSADT, I get this error:
Message : The term 'Else' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct
and try again.

Remember, please use the code formmater tools when you post to make things easier to deal with for us on the forum.

As for your query...

You are not sending / passing the result of this...

Get-ChildItem -Path "C:\Program Files (x86)" | Where-Object {$_.FullName -Like "*at&t Global*"}

... to this (or in your post you ae showing that you are)...
and you are not using the recurse switch so, if this is a subdir, it won't be found

 
if ($_.FullName -Like "*AT&T Global*") {
 Execute-Process -Path "$dirSupportFiles\agnc.exe" -Parameters "/S /v/qn /uninstall /norestart"
 }
 Else {
 Out-Null
 }

Why do these separately. Try it this way...

if ($FileToExecute = (Get-ChildItem -Path 'C:\Program Files (x86)' -filter "AcroRd32.exe"  -Recurse -ErrorAction SilentlyContinue ).FullName) 
{ "File found. Execute process started for $FileToExecute" }
Else { 'File not found. Execution process skipped' }

# File found. Execute process started for C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe

running this

$x = 2

if ($x -eq 2){
'yay'
}
else {
'no'
}

In the PowerShell ISE works. Copying and pasting into the console I got this

PS> $x = 2
PS>
PS> if ($x -eq 2){
>> 'yay'
>> }
yay
PS> else {
>> 'no'
>> }
else : The term 'else' is not recognized as the name of a cmdlet, function, script file, or operable program. Check
the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ else {
+ ~~~~
    + CategoryInfo          : ObjectNotFound: (else:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

saving it as a script also works

PS> Get-Content .\test.ps1
$x = 2

if ($x -eq 2){
'yay'
}
else {
'no'
}
PS> .\test.ps1
yay

To be safe put the else on the same line as the } immediately before it

$x = 2

if ($x -eq 2)
{
'yay'
}else {
'no'
}

Also there's no connect between you if statement and the proceeding line and the out-null does nothing
Your code probably wants to be something like
Get-ChildItem -Path "C:\Program Files (x86)" -directory | 
foreach {
if ($_.FullName -Like "*AT&T Global*") {
Execute-Process -Path "$dirSupportFiles\agnc.exe" -Parameters "/S /v/qn /uninstall /norestart"
} Else {
Out-Null
}

}

I'm presuming your looking for the directory and uninstalling the software if its present

I am not calling an uninstaller in the folder. I have need to call an executable I have in a cache locally on the computer. I'm looking for the existence of that folder because that means the software exists and can now run my executable.

Thank you for helping

Richard,

I tried your script and it worked perfectly for me! Thank you!

I also learned a little more about PowerShell.

Thanks again, great forum!
