Good Day To all,

I recently install VS 2012 ver 4.5 on my machine. After a few configurations I was able to connect to our SQL server and create a sample report, but when I try to preview the report I get the following error. I've looked into some of threads that relate to the possible problem but was still unable to resolve this problem can some one help 

Thanks in advance

Hi David,

Base on my research, the error "CreateProcess failed with Error Code: 5" error, it usually occurs due to sufficient permissions. the same behavior and error could be reproduced by launching a Remote Desktop session in Seamless or Remote Applications Integrated Locally (RAIL) mode.

Here, I suggest that you try the following steps:

1. In the Report Designer, right click the report and click "Run" to see if the report can be previewed properly in the pop-up window.
   
2. Log onto the computer with an administrator account and check the issue again. 
3.  If the report development environment is the SQL Server Data Tools (SSDT) shipped with SQL Server 2012 and you launch the SSDT via Remote Desktop Procotol (RDP) in Seamless/RAIL mode , SSDT will fail to launch Preview process. This is by design.

Here has a blog which describe this error, please refer to the following link to see the detail information about this error.
