    Can I install office 2010 if I already have office 2007 on my pc? If it is possible, will there be any interference between the 2?

    You can use both version side by side. For different architecture, the methods will differ. Pls try as below;

    (1) Office 2010 x86 & Office 2007 x86 - Office 2010 setup will ask if you want to upgrade or custom install. Do custom install, put your files in different folder from Office 2007. All your office docs will be defaulted to Office 2010. To default it to Office 2007, just rerun the Office 2007 setup.

    (2) Office 2010 x64 & Office 2007 x86 - Office 2010 x64 will not install when Office 2007 or older versions are present in your system. To install it, you need to uninstall all the older versions. After that run setup for Office 2010 first then run setup for Office 2007 or older version.

    One point to take note is while almost all different version of Office applications can co-exist in the same environment, only one version of Outlook can be installed at any time in the system. Hopefully these help.

    You can choose 'upgrade' option. That's no problem. I have tried.

    Is there a way to avoid the setup starting up when switching form Word 2007 to Word 2010?
    You know what I mean ... "Please wait while Office XXXX is being configured" box.

    I haven't installed them together yet because that used to happen with earlier versions of Office coexisting together and I just predict it might happen when I get Office 2007 and 2010 together (what about when you mix architectures?).

    set NoRereg for Office 2007

    Yes, "NoRereg" must be set for Word 2007 and for other Office 2007 programs if needed. For Word / Office 2010 no changes are needed. I have tried this and it works as expected.

    Add to a .reg file and execute: (no difference for 32 or 64 bit Windows)

    Windows Registry Editor Version 5.00
    Or execute this from a cmdline:

    reg add HKCU\Software\Microsoft\Office\12.0\Word\Options /v NoReReg /t REG_DWORD /d 1
    reg add HKCU\Software\Microsoft\Office\12.0\Excel\Options /v NoReReg /t REG_DWORD /d 1
    reg add HKCU\Software\Microsoft\Office\12.0\Outlook\Options /v NoReReg /t REG_DWORD /d 1
    reg add HKCU\Software\Microsoft\Office\12.0\PowerPoint\Options /v NoReReg /t REG_DWORD /d 1
    reg add HKCU\Software\Microsoft\Office\12.0\Access\Options /v NoReReg /t REG_DWORD /d 1
    reg add HKCU\Software\Microsoft\Office\12.0\Publisher\Options /v NoReReg /t REG_DWORD /d 1
    reg add HKCU\Software\Microsoft\Office\12.0\Infopath\Options /v NoReReg /t REG_DWORD /d 1
