11.7. Which Version of Project is Opened by @RISK?

Applies to:
@RISK 6.x/7.x, Professional and Industrial Editions
@RISK for Project 4.x

I have multiple versions of Microsoft Project on my computer. @RISK opens one version of Project, but I want it to open the other version.

Or,

@RISK works if I open Project first, but when Project isn't already running @RISK is unable to open it.

If you are comfortable editing the System Registry, you can create or change a registry key that tells @RISK which version of Project to open. (If you prefer not to edit the System Registry, and you're using @RISK for Project release 4.x, simply open your preferred version of Project before launching @RISK.)

Registry edits for @RISK up through 4.1, and for @RISK 6.1 and later:

  1. Make sure that Project is not running, then locate the Winproj.exe file and take note of the full file path. Examples:
    C:\Program Files\Microsoft Office\OFFICE11\Winproj.exe
    C:\Program Files (x86)\Microsoft Office\OFFICE14\Winproj.exe

  2. To open the Registry Editor, click the Windows Start button, then Run. Type REGEDIT and click the OK button. (In some versions of Windows, you can do a search for the REGEDIT application.)

  3. When the Registry Editor window appears, navigate to
    HKEY_LOCAL_MACHINE\Software\WOW6432Node\Palisade
    in the left-hand pane, or in 32-bit Windows navigate to
    HKEY_LOCAL_MACHINE\Software\Palisade
    In the right-hand pane you will see two string values called Main Directory and System Directory, and possibly some additional values.

  4. If Project Path appears in the right-hand pane, double-click it and edit the path to match the path you noted in step 1.

  5. If Project Path does not appear in the right-hand pane, right-click an empty spot in the right-hand pane and select New » String Value. Name the new string value Project Path, with a space between the two words. Double-click the name Project Path and edit in the path that you saved in Step 1.

  6. Test your edit by launching @RISK. If the correct version of Project does not come up, edit the value of the Project Path string. If the correct Project comes up, close the Registry Editor by clicking File » Exit.

Special note for @RISK 6.0:

In @RISK 6.0, the Registry key is HKEY_CURRENT_USER\Software\Palisade\@RISK for Excel\6.0\Project Version and not HKEY_LOCAL_MACHINE\Software\Palisade\Project Path. Beginning with 6.1, HKEY_LOCAL_MACHINE\Software\Palisade\Project Path is preferred, but if it is not found then HKEY_CURRENT_USER\Software\Palisade\@RISK for Excel\6.0\Project Version will be checked.
