This Wiki will explain how to install different Web Client Controls on same physical machine.

Background

Web Client Controls are used for various file handling operations (upload, check-in, check-out) in eB Web user interface. For different eB versions different Web Client Control version are used (if incorrect version of WCC is installed then all file handling features will be disabled).

When trying to install different WCC versions on same machine error message is received “Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel”.

This issue is related to Bug in installed (which will be fixed in future releases).
