Acronis Disk Director 10 Removal

I am attempting to remove Acronis Disk Director 10 from a Server 2003 64 bit machine. I have followed instructions below:

1.Go to the Start | Run... Type "regedit" and click OK.
2.In the registry editor, navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4D36E967-E325 -11CE-BFC1-08002BE10318}.
3.Remove the 'snapman' entry from the "UpperFilters" values. This will unregister the snapman.sys driver as a PnP filter for disk devices.
4.Check the "LowerFilters" Key (if it exists) and remove any reference to Snapman
5.Next, navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{71A27CDD-812A -11D0-BEC7-08002BE2092F}.
6.Remove the 'snapman' entry from the "UpperFilters" values. This will unregister the snapman.sys driver as a PnP filter for logical volume devices.
7.Check the "LowerFilters" Key (if it exists) and remove any reference to Snapman
8.Next, navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\snapman
9.Add a REG_DWORD value named DeleteFlag with a value 1 inside this 'snapman' key. To do this, go to the Edit | New | DWORD Value. Type the name 'DeleteFlag', then double-click the icon next to it to enter the value of 1. Click OK. Next, double-click the Start REG_DWORD value inside the snapman key to change its value to 4 (disabled).
10.Reboot
11.Navigate to C:\windows\system32\drivers and rename snapman.sys to snapman.old. if snapman.sys is not found also look for snman380.sys.
12.Reboot (Important: This will insure that Snapman.sys have been removed successfully. If it has not, the machine will blue screen. You will need to reboot the computer into safe mode and ensure that the process is completed properly before you will be able to boot 'normal' again.)

However. I also have a snapman.sys file in C:\Windows\syswow64 and I need to know if it can just be renamed like the file in c:\windows\system32\drivers or if there would be more registry entries I need to be concerned with.

Thanks.
