Crystal Reports 10 Compatibility with Windows Server 2008 R2

Question

Hello I'm a developer and I'm in the process of migrating my ASP.NET application that uses crystal reports 10 from a win2k3 server to a win2k8 R2 server.
First of all, is CR 10 compatible with windows server 2008 R2?
The application is up and running on the new server, the only thing that fails is the reports. I get the following error message:
Error in file ....c:\windows\temp\{TEMP_FILE_NAME}.rtp
Failed to create the Crystal Query Engine.
This occurs at report.load(..)
I did already grant NETWORK SERVICE access to Temp and ran the CR redistribute msi that came with Visual Studio 2008 - CRRedist2008_x64.msi.
Please help

YESSSS!!!! IT WORKS!!
Finally, after days of installing, uninstalling, setting permissions, crawling through process monitor output.. I finally have it working.
For anyone with the same problem, here's what worked for me:
I had to use the 32-bit runtime
set application pool to 32-bit
grant the following permissions based on the different errors listed below:
Error in File UNKNOWN.RPT
- Give NETWORK SERVICE list permission on C: Drive, run a report, then remove NETWORK SERVICE from the list (weird, but works, and I had to do this every single time I setup Crystal Reports on a new computer so far).
- You might also have to set correct permission on 'Temp' if u get still get this error.
Error in file ....c:\windows\temp.rtp
Failed to create the Crystal Query Engine
- Grant correct permission to C:\Program Files (x86)\Business Objects (your path may vary)
(For me it was giving Users Modify permission to Business Objects folder)
Unknown Query Engine ErrorError in File C:\Windows\TEMP\.rpt:
Unknown Query Engine Error
- Switch application pool to 32-bit.
- Make sure Crystal Reports Runtime is 32-bit (CRRedist2008_x86.msi)
Thank you guys so much for all your help and sticking through this with me.
