vbscript filesystemobject permission denied - vbscript

Question

I'm having a problem with Trend OfficeScan Patterns filling up the C:\ drive (no other drives available to change directories) and I'm getting a permission denied error accessing "C:\Program Files\Trend Micro\OfficeScan\PCCSRV\WSS\patterns" running the below script. As I'll be using this script for a few sites, and to make it easy to implement for my colleagues, I don't want to play around adding various permissions.
I tried changing: PatternLocation = (strValue & "WSS\patterns\") to PatternLocation = ("""" & strValue & "WSS\patterns\""") and I get 'Path not found'. Are there any VBScript experts that may be able to recommend an impersonate method to overcome the permissions denied?

This is the working script with a few changes for anyone who might find it useful:
'Variable to locate HLM.
const HKEY_LOCAL_MACHINE = &H80000002
Set fso = CreateObject("Scripting.FileSystemObject")
'Checks if the operating system is x86 or x64
Set objShell = CreateObject("WScript.Shell")
osType = objShell.ExpandEnvironmentStrings("%PROCESSOR_ARCHITECTURE%")
'The dot refers to the computer this vbscript has been run on.
strComputer = "."
'Provides connection to the registry.
Set objReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" &_
strComputer & "\root\default:StdRegProv")
'Checks the bit for the operating system
If osType = "x86" Then
'Checks registry for Trend folder path.
strKeyPath = "SOFTWARE\TrendMicro\OfficeScan\Service\Information"
Elseif osType = "AMD64" Then
strKeyPath = "SOFTWARE\Wow6432Node\TrendMicro\OfficeScan\service\Information"
End if
strValueName = "Local_Path"
objReg.GetStringValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,strValue
'If the registry path is empty it won't install the scheduled task and alert you.
If IsNull(strValue) Then
msgbox("Trend Micro is not installed.")
else
PatternLocation = (strValue & "WSS\patterns") ' folder to start deleting (subfolders will also be cleaned)
'msgbox(PatternLocation)
end if
startFolder = PatternLocation
OlderThanDate = DateAdd("d", -1, Date) ' 1 days
DeleteOldFiles startFolder, OlderThanDate
DeleteEmptyFolders startFolder
Function DeleteOldFiles(folderName, BeforeDate)
Dim folder, file, fileCollection, folderCollection, subFolder
Set folder = fso.GetFolder(folderName)
Set fileCollection = folder.Files
For Each file In fileCollection
If file.DateLastModified < BeforeDate Then
fso.DeleteFile(file.Path)
End If
Next
Set folderCollection = folder.SubFolders
For Each subFolder In folderCollection
DeleteOldFiles subFolder.Path, BeforeDate
Next
End Function
Function DeleteEmptyFolders(foldername)
For Each Folder In fso.GetFolder(foldername).SubFolders
DeleteEmptyFolders(Folder.Path)
If Folder.Files.Count = 0 and Folder.SubFolders.Count = 0 Then
fso.DeleteFolder(Folder.Path)
End If
Next
End Function
