This article was previously published under Q284853 IMPORTANT: This article contains information about modifying the registry. Before you

256986 Description of the Microsoft Windows Registry
SYMPTOMS
In Microsoft Project 2000, when you attempt to save a project in Microsoft Project 2000 format, you may receive the following message:
'File name.mpp' may contain features that are not compatible with the Microsoft Project 98 format. If you keep the project in this format, you may lose data for incompatible features. To see what might be lost, click Help.
You can:
- Keep the Microsoft Project 98 format, which leaves out data for any incompatible features, and which may cause your schedule to change. (Note that you may also lose Baseline Data).
- Cancel the save operation. You can then save a copy in the latest Microsoft Project format.
If you select the first option, the project is saved in Microsoft Project 98 format. If you select the second option, you are returned to Microsoft Project 2000 and the project is not saved.
CAUSE
This behavior can occur if an invalid registry value exists in the following registry key:
HKEY_CLASSES_ROOT\MSProject.MPP\CLSID
An invalid registry value can occur for either of the following reasons:
- Both Microsoft Project 98 and Microsoft Project 2000 are installed on the same computer. Both versions of Microsoft Project use some of the same system settings and registry keys. Microsoft recommends that you not install both Microsoft Project 98 and Microsoft Project 2000 on the same computer. This configuration is not supported by Microsoft Product Support Services.
-or-
- A prior installation of Microsoft Project 98 affected Microsoft Project 2000 when you installed Microsoft Project 2000.
WORKAROUND
To avoid this behavior, do not install Microsoft Project 2000 on a computer that already has Microsoft Project 98 installed, unless you choose to remove Microsoft Project 98 during Microsoft Project 2000 Setup.
If you have already installed Microsoft Project 2000 on a computer with Microsoft Project 98 (and you did not remove Microsoft Project 98 during Setup), uninstall Microsoft Project 98 and then reinstall Microsoft Project 2000. To do this, follow these steps: - On the Start menu, point to Settings, and then click Control Panel.
- In Control Panel folder, double-click Add/Remove Programs.
- In the Add/Remove Programs dialog box, select Microsoft Project 98, and then click Remove.
- Follow the instructions to completely remove Microsoft Project 98.
- Insert the Microsoft Project 2000 installation CD. (NOTE: If Microsoft Project 2000 Setup starts automatically, click Exit to close the Microsoft Project 2000 Setup dialog box.)
- Click Start, point to Settings, and then click Control Panel.
- In the Control Panel folder, double-click Add/Remove Programs.
- In the Add/Remove Programs dialog box, select Microsoft Project 2000. If you are running Microsoft Windows 2000, click Change. If you are running Microsoft Windows 95 or Microsoft Windows 98, click Add/Remove.
- When the Microsoft Project 2000 Maintenance Mode dialog box appears, click Repair Microsoft Project, and then click Next.
- Click Reinstall Microsoft Project, and then click Finish.
- Follow the instructions in the Installation Wizard to complete the reinstallation of Microsoft Project 2000.
NOTE: If you want to keep Microsoft Project 98 instead of Microsoft Project 2000, follow similar steps but uninstall Microsoft Project 2000 and reinstall Microsoft Project 98. WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
If you suspect that the registry key contains an invalid value, follow these steps: - Quit Microsoft Project if it is currently running.
- On the Start menu, click Run.
- In the Run dialog box, type regedit in the Open box, and then click OK.
- In the Registry Editor, select the following key:
HKEY_CLASSES_ROOT\MSProject.MPP\CLSID
- In the right pane, in the Name column, click (Default).
- On the Edit menu, click Modify.
- In the Edit String dialog box, in the Value data box, type the following value:
{98D1C0D2-DADB-11D1-92CA-00C04FB925F1}
Click OK. - Select the following key:
HKEY_CLASSES_ROOT\MSProject.MPP.9\CLSID
- Ensure that the value for this key matches the value that you typed in step 7.
- On the Registry menu, click Exit.
- Restart your computer.
