Why do I receive the error "Unable to Install Extensions" when attempting to run the Web Client?

Resolution:


Problem Description:

When attempting to run the Web client, an error "Unable to Install Extensions" is received. User has Administrative privileges on the workstation and is manually able to run the CaliberRM Web Extensions installer successfully, however always receives this error when attempting to load the web client.

If Java Console has been enabled, there will be a stack trace similar as below:

CaliberRM 9.0.847.0
caliberrm.extensions.path=null
DLLs are not installed.
java.io.IOException: The system cannot find the path specified
at java.io.WinNTFileSystem.createFileExclusively(Native
Method)


Resolution:

The Web Client expects the path of the extensions directory to be the default path of C:\Windows. If this directory has been changed from the default path, you are likely to receive this error.

If possible, the expected directory structure of C:\Windows may be created, manually copying the files (CRMOSSupport.dll, SBTBJavaUtils.dll, jvb.dll, CRMMorningGlory.dll, jdic.dll, CaliberCommon.dll, mfc71u.dll, msvcp71.dll, msvcr71.dll) into this directory and relaunching CaliberRM for the Web.

Also the drive is expected to be the C:\. There have been environments seen with Citrix or the like where there is no C:\ at all due to company security policies. Since the path is hardcoded, there is no workaround for this issue other than ensuring that the C:\ exists. One option may be to allow clients to load the web client directly to their workstation or home computer without going through a virtualized environment. Another may be to have the user install the win32 client, and obtain VPN access in order to run the application.
