How can I update this .HTA to be used in Win7

Question

I have an HTA that we use to gather our servers disk space, and it exports that information into a CSV file. Since we upgraded to Win7, it will not export because it uses WinXP "SAFRCFileDlg.FileSave". I am looking for a way to use this HTA with Win7, but I need to know what I can do to get around this XP script. I cannot add the dll from xp.

I wanted to post the entire script so that you can see all that is involved in it. The issue is in the "Sub Export". Any help will be appreciated. This script is nice and easy to use, it displays all of the information nicely, but I can't get it to export the data.

If it's an HTA add this somewhere in the body.

<OBJECT id=Dlg classid="CLSID:3050F4E1-98B5-11CF-BB82-00AA00BDCE0B" width=0 height=0>

Then use this code to open the dialog.

strUPath = objShell.ExpandEnvironmentStrings("%USERPROFILE%") & "\Desktop"
strStartPath = strUPath & "\Select a file"
strFilter = "Text (*.txt;*.csv)| *.txt;*.csv|VBScript (*.vbs;*.vbc)|*.vbs;*.vbc|HTML (*.htm;*.html;*.hta)|*.htm;*.html;*.hta|All Files (*.*)|*.*|"
strCaption = "Select a File to Replace"
strSelectedFile = Dlg.openfiledlg(CStr(strStartPath), , CStr(strFilter), CStr(strCaption))
