I've logged a ticket with Symantec when I couldn't get the MR2 to apply porperly. After the update, i couldn't load the forms and have errors.  I've found the workflow packages copied to C drive while the release folders updated in D drive. They replied to try these steps below.

(Do make sure to take a backup of the server and the database in-case you want to get back to the same status after the upgrade.)

(copied from their email)

1. - Copy the Workflow Designer folder and all sub files\folders that were copied to C: during the failed upgrade to the Workflow Designer folder on your install drive.  You will need to close any Workflow tools and windows and then stop the Logicbase2006ServerExtensions service and stop IIS (from cmd prompt iisreset /stop).
2. - Once the files are copied over start IIS (from cmd prompt iisreset /start) and start the Logicbase2006ServerExtensions service.
3. - Open Process Manager portal and go to Admin > Data > Application Properties.
4. - Click the Action button (lightning bolt icon) and choose Delete Profile Definition.
5. - Close Process Manager.
6. - Run the ServiceDesk MR2 install.
7. - During the installation choose New for the install.  You need to choose this option as there are no longer any Application Properties.
8. - When you get to the database settings section of the install choose update existing database

I've just completed this testing and now i have 2 sets of Application properties even though i've deleted it before trying these steps. The processmanager seems to be loading fine, I haven't tried creating a ticket yet but I can view the new technican submit form. Just had another email from Symantec, they say to delete Application properties and try again (for the 2nd time).

If anyone wish to try the steps above, please let us know how it goes for you. Thanks.
