I download AlfrescoCommunity-2.0-Linux-x86-Install and install it on Ubuntu 7.0.4 under /tmp/Alfresco and then install AlfrescoWCMCommunity-2.0-Linux-x86-Install and follow the installation wizard until "Choose Existing Alfresco Location" window and specifiy the "Destination Folder" to /tmp/Alfresco and then click on next. It immediately displays the error msg box "No Alfresco installation found at this location". The Alfresco installation do exist under /tmp/Alfresco.
Please help.
