SOLVED Can't read registry with powershell and sccm

[pcb]

For some reason, I can't get SCCM to read the registry with a simple powershell command.
Code in question:
try {
$registryKey = Get-Item -LiteralPath "HKLM:\Software\LCC\Device"
$behavior = $registryKey.GetValue("Behavior", $null)
} catch {
$behavior = $null
}
Write-Host $behavior
pause

When called with SCCM on the client machine I get this error:
Get-Item : Cannot find path 'HKLM:\SOFTWARE\LCC\Device' because it does not exist.
At C:\WINDOWS\ccmcache\n\InstallOESClient.ps1:3 char:20
+ $registryKey = Get-Item -LiteralPath "HKLM:\SOFTWARE\LCC\Device"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (HKLM:\SOFTWARE\LCC\Device:String) [Get-Item], ItemNotFoundException
+ FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetItemCommand

But if run with Psexec.exe -i -s powershell.exe
PS C:\windows\ccmcache\n> powershell -ExecutionPolicy Bypass .\InstallClient.ps1

It outputs the value as expected... what is going on here? Is there some special trick to reading the registry with powershell? I have several scripts that write to this same key and that is no problem.

how are you deploying the script? Is it a x86 issue?

With an application in SCCM - command = PowerShell.exe -ExecutionPolicy Bypass -Command ".\InstallOESClient.ps1"

And apparently that was the problem... I don't really know for sure, but I think somehow a special character got into the command. I looked it over several times and everything looked exactly right, but I retyped the command from scratch and now it is working.
