Set-RegistryKey -Type Binary : "Input string was no in a correct format"

The Toolkit General Discussion

I’ve got |-delimited data in the form:

SiteCode|Abbrev|Login|Password
7777|its|0x33,0xfc,0x00|0x33,0xfc,0x00
etc.

So I try:

<code>
$siteData = Import-Csv Sites.csv -Delimiter &#039;|&#039;

$strSite = &#039;7777&#039;

$objMatch = $siteData | Where-Object {$_.SiteCode -eq $strSite}
$strLoginTemp = $objMatch.Login
$strLogin = &quot;([byte[]](${strLoginTemp}))&quot;

Set-RegistryKey -Key &#039;HKCU\Software\Dynix\HorizonS75\Connect\HORIZON&#039; -Name &#039;Login&#039; -Value $strLogin -Type Binary
</code>

I get ‘Input string was not in a correct format’
It can change the value directly with Set-ItemProperty, but Set-RegistryKey doesn’t like it.
What am I doing wrong?
