Migratiing CR XI to 64 bit Windows and RDC ASP

Question

Which is the best time/cost strategy for the following problem:
We have developed a WEB application that is running on a WINDOWS Server 2003 (32bit). The aplication was programmed to use de COM+ environment with asp for the Activex viewer.
We are migrating it to a new machine with WINDOWS SERVER 2003 R2 Standard X64 EDITION.
On our first try on this machine (we didn´t apply the SP´s), CR developer performed OK, but not the viewer.
Now we have the SP2, SP3 and SP4, and Crystal Reports 2008.
Wich is our best strategy? Because we found out that unfortunalty CR 2008 which is 64 bit enabled does not support RDC, and reprogramming the system can be quite time consuming or the Service Packs are oru answers?

Answer 1

The best and most economic strategy is to install the Service Packs and follow the instruccions found in http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/848968f3-baa0-46f9-b1e6-ef81dd09b015.mspx?mfr=true
Deployment Guide  APENDIX D.
It enables IIS 6.0 to run 32-bit Web applications on 64-bit Windows using the Windows-32-on-Windows-64 (WOW64) compatibility layer.
