A Microsoft Visual Studio.NET application uses Crystal Reports 10 for Visual Studio.NET SDK as the reporting development tool. When the application is deployed to a computer that does not have a C: drive, the following error message appears: "Load Report Failed". It is common to not have a C: drive on Terminal servers and Citrix servers.

To resolve this issue:

This error message appears because the application sets registry values that point to the C: drive. To resolve the error message, use the following steps to change these registry values in the Registry Editor.

**Warning: The following resolution involves editing the registry. Using the Registry Editor incorrectly can cause serious problems that may require you to reinstall the Microsoft Windows operating system. Use the Registry Editor at your own risk. It is strongly recommended that you make a backup copy of the registry files (System.dat and User.dat on Win9x computers) before you edit the registry.

1. On the Start menu, click Run.
   
   
2. In the Run dialog box, type Regedit then click OK.
   
   
3. In the Registry Editor browse to the following subkey:
   HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\10.5\Report Application Server\InProcServer\LocalConnectionMgr
   
   
4. Right-click the ConnectionDirectoryPath string value, then click Modify.
   
   
5. In the Value data text box, change "c:\" to the drive letter where the following directory exists (You may need to search your computer to find where this directory exists):
   \Program Files\Common Files\Crystal Decisions\2.5\bin.  Click OK.
   
   
6. Right-click the LocalConnectionMgr subkey, click New then click String Value.
   
   
7. Name this String Value "ReportDirectoryPath".
   
   
8. Right-click the ReportDirectoryPath string value and click Modify.
   
   
9. In the Value data text box, type the same drive letter as you typed in step 5.

Please note that the article refers to Crystal Reports 10, but it also works for Crystal Reports XI Release 2. Just search the registry for ConnectionDirectoryPath where a value is 
specified. (It should be HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\10.5\Report Application Server\InProcServer\LocalConnectionMgr for the current versions of all Wasp products.)
