OS=Small Business Server 2003

Error message occurs when trying to install exchange service pack 2 on SBS 2003.

Error is
Multiple components cannot be assigned the requested action becacuse:
-you must have exchange server 2003 installed on this machine before installing this microsoft Exchange server service pack.

Now when the operating system was installed updates and service pack 1 was installed before the small business server integrated setup was finished  this caused the first problem which was that the setup could not continue due to the following error

'This computer cannot be upgraded to OEM version of small business server' this was resolved by changing the following reg key
HKLM\software\microsoft\smallbusinessserver\IsRunFromWeb and set the value to Decimal 1

this allowed us to continue with the small business server integrated setup. but when i now try and run the update for exchange service pack 2  i get the above error.

does anyone know where i need to look in the registry to get round this problem.

uninstalling exchange is not a option.
