BigIP Report Old

I setup another vm, brand new vm running windows 7. Tried version 4.7.3 but it fails with this error:

PS C:\Users\Administrator\Documents\BigIpReport> .\bigipreport-4.7.3.ps1You must provide a value expression on the right-hand side of the '-' operator.At C:\Users\Administrator\Documents\BigIpReport\bigipreport-4.7.3.ps1:1871 char:57+ $ruleScope = $Global:irules | Where-Object { $_.name - <<<< in $Bigipreportconfig.Settings.iRules.iRule.iRuleName -and $_.loadbalancer -in $Bigipreportconfig.Settings.iRules.iRule.loadbalancer } + CategoryInfo : ParserError: (:) [], ParseException + FullyQualifiedErrorId : ExpectedValueExpression

I tried the same files on my current system, script runs, I get the results, but same issue. I'm not seeing the export and other options at the top
