•	Microsoft Office 2003 • Microsoft Office Excel 2003 • Microsoft Office PowerPoint 2003 • Microsoft Office Word 2003

•	Microsoft Office 2000 • Microsoft Excel 2000 • Microsoft PowerPoint 2000 • Microsoft Word 2000

If the file was saved in a prerelease version of one of the programs that are listed in the "Applies to" section, you may receive one of the following messages.

By default, some Open XML files that were saved in the prerelease versions of the 2007 Office programs cannot be opened by the Compatibility Pack for the 2007 Office system.

To work around this issue, an administrator can disable a policy by using one of the following methods, as appropriate for the situation.

Notes

•	These methods will enable you to open an Open XML file that was saved in the Beta 2 version of PowerPoint 2007. In these situations, you will receive message 2 in the "Symptoms" section. Additionally, the file will open.
•	These methods will enable you to open an Open XML file that was saved in the Beta 2 version of Excel 2007 or in the Beta 2 Technical Refresh version of Excel 2007. In these situations, you will receive message 4 in the "Symptoms" section. Additionally, the file will open.
•	These methods will not enable you to open an Open XML file that was saved in the Beta 2 version of Word 2007. The only workaround is to open the file in the original release version of Word 2007 and then resave the file. When you do this, the file will be saved in the newest file format. The recipient of the document can then use an earlier version of Word with the Compatibility Pack to open the file.

Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.
