Microsoft Office and Windows Vista and a Sony Vaio

Hi,

Would be very greatful for any help as stuck with an install. Relatively computer literate but not working in the field

I have a new vaio and I am having great difficulty getting any software to install office.

I uninstalled the office 2007 trial when i recieved the machine. Uploaded office 97 as I had an upgrade standard version of office. Then tried to upload my 2003 version. I could put the key in but would not start the install.

Then when i went back to 1997 i was getting the erorr message that not enough memory to run the programme.

I have read a few threads and tried a few thing. Tried to remove everything and start again. Got rid of everything with a Microsoft office prefix by taking it off the programmes list from control panle, using install clean up, and from installer file of windows. However i have 97 activation assistant and setup in the start menu and the old school 1997 install wizrd freezes if i try to remove any remainig component.

I now have a full student teachers version of office in addition to other version.

Basically i would like to get any version to work. Preferably 2003, if not i take the 2007 version for 60 days as away from home and stuff i need to do on the laptop ASAP. Or even 1997 would be fine.

Any help would be great as have come to the end of the line. Is this a case of a little knowledge is a dangerous thing?

Cheers

Crispin
