The issue:

 

The desktop client does not start when some of the special folders are network-mapped and inaccessible.

For example, two of the special folders like Pictures, Downloads, Desktop, etc. are mapped to a network resource, as shown in the screenshot, and the network resource is inaccessible.

In that case, the Desktop Client does not start even after a clean install.

When two or more special folders are mapped to network resources and the resources are inaccessible, a specific check from the Syncplicity system returns the same result, which is the reason for the “An item with the same key has already been added“ error.

When you try to open the special folders, an error occurs:

Workarounds:

1. Fix the access/connection to all special folders which used the network paths.

2. Change the path of the special folders in order to point to a local destination.

 

Fix:

It is planned to be fixed in some of the future releases.
