title: Crystal Reports Viewer does not display in browser on one server, yet does on an almost identical server
body: <p>I have two Amazon EC2 instances that are just about exactly identical. (set up the first one, made an image of it and then created a new instance from this). The only difference on the 2nd server is that the application directory is on a side drive (E), not the main drive (C). If i navigate to the site hosted on the first server (which has the application directory on C) the report displays. On the other server where the directory is on the E drive the page loads but there is no report displayed - It just appears as a blank page. </p>
  
  <p>I installed and reinstalled the CRforVS runtime (using the older 13.0.2 on both) yet this doesn't seem to let us view the report on the 2nd server. Is this because when the MSI runs it installs to C and the site contained on E is not looking in the correct place for the resources? Listed below is the section of my web.config that handles the CR runtime.</p>

  <p>Thank you.</p>
  
  <p>edit - i found a little information that deals with if there is no "C" drive - <a href="http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/d02f7cd3-f18b-2d10-55ad-dab2200f68fc?QuickLink=index&amp;overridelayout=true&amp;53240414858625" rel="nofollow">http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/d02f7cd3-f18b-2d10-55ad-dab2200f68fc?QuickLink=index&amp;overridelayout=true&amp;53240414858625</a></p>
  
  <p>wasn't sure if this applied in my situation since there is a c drive, just the site is not located on this drive.</p>
