After installation of Adobe Professional 7, 8 or 9, you may get the following error when you start Excel 2003 or Excel 2007:
“Compile Error in Hidden Module: Distmon”
The cause of this error is PDFMaker.xla, which loads at startup. Since Adobe Professional 8 uses DLL-addins to add the toolbar in Excel, you can safely delete the PDFMaker.xla file on your computer.
Sometimes PDFMaker.xla is located in your profile directory:
C:\Documents and Settings\<user>\Application Data\Microsoft\Excel\XLSTART\PDFMaker.xla
Other times, PDFMaker.xla can be located in your Program Files directory.

In some cases after upgrading to Excel 2007, you may get the following error:
The file you are trying to open .xlsx is in a different format than specified by the file extension. verify the file is not corrupted and is from trusted source before opening the file. Do you want to open the file now?

In Office 2007, we have the possibility to personalize our Quick Access Toolbar (extension: qat). Every modification, that differs from the default Quick Access Toolbar, will be saved in the following directory C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Office (where %username% must be replaced by your current login name)
