Outlook PRF on Server 2008 R2

Hi,

I have a Outlook PRF file that works perfectly with 32 bit office on Windows 7 but when I try it on a 64 Windows 2008 R2 server it doesnt seem to run as Outlook displays the run through dialog box for new profiles.

This is the command:

"C:\Program Files (x86)\Microsoft Office\Office14\OUTLOOK.EXE" /importprf "\\SERVER\software\Office2010\Outlook_Only.prf"

I've also tried a VB script with these commands which also doesnt work:

oShell.RegDelete "HKCU\Software\Microsoft\Office\14.0\Outlook\setup\First-Run"
 oShell.RegWrite '"HKCU\Software\Microsoft\Office\14.0\Outlook\setup\importPRF","\\SERVER\software$\Office2010\Outlook_Only.PRF", "REG_SZ"
 oShell.RegWrite "HKCU\Software\Microsoft\Office\14.0\Outlook\UserData","1","REG_DWORD"

Anyone any ideas?

Thanks
