How do I do a Clean Uninstall of the CA PPM Microsoft Project (MSP) Interface? 

Sometimes, due to permission restrictions or other issues on the machine, some of the MSP components do not get uninstalled on their own. If that is the case, a manual uninstall is needed to remove the remaining components. Doing a clean uninstall / install is especially recommended if running into issues during an upgrade of the MSP Interface. 

Below are the steps to do a clean uninstall:

1. Uninstall the following components from Control Panel (if there are any duplicates of any of the components delete those as well):

• CA PPM Microsoft Project Interface 
• CA PPM Schedule Connect
• CAClarityAddin
• Open Workbench (if installed) - Note, prior to uninstalling OWB, if you have any custom views for OWB, make sure to save these in a separate folder prior to the uninstall. 

2. Clean out the Registry:

• On the workstation, go to Start and type 'regedit' in the search field. Select regedit.exe
• Select File -> Export and enter a File Name to store the back-up of the registry
• Once finished creating a backup, delete the following keys if they exist: 
  • HKEY_CURRENT_USER\Software\Niku
  • HKEY_LOCAL_MACHINE\Software\Niku (You may need to drill down to the Wow6432 folder to get to the Niku folder: HKEY_LOCAL_MACHINE\Software\Wow6432Node\Niku)

Please note that some of the keys may not exist; also, deleting each key will correctly delete all of their sub keys. 

3. Go to Add/Remove Programs again and check that there is no trace left of the products that you have removed in step 1

4. Delete the following folders if they are still listed: 

• C:\CA\CA PPM MSPInterface
• C:\CA\PPM Setups
• C:\CA\PPM\CA PPM Schedule Connect

Please note that the folder location is dependent on where the MSP Interface was installed:

• If you installed the 32 bit Interface, the folders may be instead found in: C:\Program Files (x86)
• If you installed the 64 bit Interface, the folders may be instead found in: C:\Program Files

5. Clean out Visual Basic:

• In MSP, go to View > Macros > Visual Basic Editor
• Expand ProjectGlobal, Expand Modules
• Delete the modules that start with either CA_ and Niku_ (Right click the module and select 'Remove ...' 
• Click ‘No’ to the message that pops up ‘Do you want to export <Module Name> before removing it?’
  

         (That is asking if you want to export the files, which is not needed)

• Expand Microsoft Project Objects, Double-click on Thisproject
• Select everything in the right panel and delete it
• Save and exit VB

 6. Verify the correct Trust Center Setting is set:

• Go to File > Options> Trust Center > Trust Center Settings
• Make sure "Enable all macros" is selected

7. Reinstall the MSP Interface.

• Ensure the bit level of the MSP Interface being installed matches that of MSP.
  • See KB KB000124188 for how to check what MSP bit level MSP is using, and which CA PPM Integration bit level should be installed based on the MSP bit level. 
• Also make sure the version being installed is the same version and patch level as that of PPM. It can be found in PPM by going to Home->Account Settings->Software Downloads.

8. If using a proxy, reenter the Proxy Host and Proxy Port in the setup window in MSP. See the steps to renter proxy details found in KB: KB000072865
