write-n-cite installation error

Hey everyone,
I have Win7 and Office 2010 (only Word, Powerpoint and Excell) and am trying to install the write-n-cite (WnC4Install64). It's one of the components of RefWorks.
When I want to install the 64-bit version, it says "Microsoft VSTO 2010 Runtime (x64)" is pending then it tries to install it and after than during the installation of WNC, it says "Office is 32-bit, please use write-n-cite 32bit version and continue the installation".
Then I try to install the 32-bit version and it says:
"Office is 64-bit, please use write-n-cite 64bit version and continue the installation".

Things I've done:
1- Unisntalled the Office entirely and reinstalled it
2- Tried to update Windows and Office, it was somehow successful but some updates were not installed for some unknown reason
3- This is the WNC4 that I'm trying to install. The 3rd version can be easily installed but it's not as good as the 4th.
4- My office is 64 bit BTW
5- The problem is not VSTO I think! That guy is already installed but even if I uninstall it manually, it doesn't solve the problem
6- I was told by the support that perhaps there is a component like Access that is in 32 bit and is causing this problem but I don't know what that component can be!
I have many Microsoft development stuff installed from 2005 to 2008 to 2010 blahblahblbal

Please let me know if can think of anything to solve this problem.
Thank you

Hi BB,

Here causing trouble again?.................and you lot beat our boys at men's curling?

OK mate, joking aside............ Office 2010 is still 32 bit................. you need to delete and reinstall as 32 bit then your other stuff should work. Trying to run MS Office as 64 bit is not a good idea, even though it allows big files.

Hope that helps,

Johnno:D

Hi Nihil,
LOLLLLLLLLLL I should tell you about my recent losses to give you an idea of what we're paying for beating your men :))
Thanks for the response. I'll give it a shot. For the records, people told me that Mendeley is a good free alternative so I'm gonna see how things go ...
Cheers
