When installing the increment you must install the exact same component as was installed for SCM V13 GA release. With the SCM Client there are two different types - Full Client and Workbench Only. If you try to install Increment 2 of the wrong type of client you will get an error message like this.
If you installed SCM v13 GA release of the 32-bit Full Client, and then try to install the SCM V13 Increment 2 of the 32-bit Workbench Only client you will see something like this:
Error 2711. The specified Feature name ('<userid>') not found in Feature table
<Please see attached file for image>
<Please see attached file for image>
If you receive the first message beginning with "Error 2711" this means you need to install the CA SCM V13 Increment 2 of the 32-bit Full Client.
If you receive the second message beginning with "Error 2727" this means you need to install the CA SCM V13 Increment 2 of the 32-bit Workbench Only Client.
As always, please contact CA Technologies support for CA Harvest Software Change Manager if you have further questions.
