I recently upgraded to Office 2007 and my computer instantly slowed down. I noticed that Office 2003 is still listed in Add/Remove Programs on the Control Panel. Is Office 2003 needed on my computer for Office 2007 to work properly?

No, one can install Office 2007 without to have Office 2003 or, if it is an upgrade version, you have to insert the Office 2003 installation cd to verify, whether you are allowed to install the upgrade version. But there gets nothing installed from the Office 2003 version.

Thank you for your response. I appreciate it.

Also, if you remove Office 2003, you'll need to reinstall 2007. LIR

Thank you for your response. I uninstalled 2003. The problem is that our technical manager installed 2007 on my laptop and then he was recently let go and took the disks with him. I can use Word with no problem, but I am getting the error: "Microsoft Visual Basic-Compile error in hidden module: AutoExecNew" whenever I open Excel and: "Microsoft Visual Basic-Compile error in hidden module: DistMon" whenever I close Excel. The program seems to still work so I will probably just learn to live with it. Thanks again.

Hi, This appears to be a problem with an add-in that is not compatible with Excel 2007. This Microsoft article describes the issue and points to ways of dealing with it. Older versions of Adobe Acrobat can cause this and it also refers to Norton anti-virus. Regards
