Lumira1.27 failed installation Oracle 11-jdbc driver and MSSQL 2012 drivers

Hi I just started Lumira 1.27 POC.

I have Lumira installed on a Terminal server with 64 bits.

OS version is Windows 2008R2

OS version W2K8R2_SP1_STD_X64

Service Pack1

CPU is Dual 2.70 GHZIntel XeonR

Memory 4096MB

I used the File->Preferences->SQL Drivers to install

1. Oracle 11 - JDBC Drivers. - I placed jdbc6.jar into C:\Program Files\SAP Lumira\Desktop\plugins
2. MS SQL Server 2012 JDBC Driver. This I use sqljdbc4.jar

After I choose to install the above .JAR files, it shows GREEN indicating installed. It then prompts me to close the Lumira and restart to take effect.

But after I restart the application, it shows not installed and it still has RED CROSS.

Can someone point out if I missed any step here?

I have been stuck here for 2 days...Tks.
