I bought Microsoft Office 2010 Family and Student, but i can't instal it.
The installation stop at 3/4 and an error message appear:
Error 1935. An error occurred during the installation of assembly {3FA0170E-227C-37C7-BAC0- 64691a992C81}. HRESULT : 0x80070002.

I found a lot of topics on this subject but no solution to my problem.
I've tried lot options:
I've unloaded the trial version of Office 2007.
Install .Net framework 1.1, 2.0, 4.0.

HELP.

If anyone can help me, i'm desperate.
thank you

I've unloaded the trial version of Office 2007.

You may have remnants from the previous Office 2007 installation
Use the trial version of Revo uninstaller to remove leftover files Revo Uninstaller Pro - Uninstall Software, Remove Programs easily
Use the 'Forced Uninstalled feature'

I had exactly the same problem, tried for over 2 hours to load Office 2010 Home & Student to no avail, in frustration I rang Microsoft support, and had to give them via some software access to my computer and 30 minutes later........................perfect, I know we used the cmd command, then had to type in some Dos (wish I could remember what I typed) I know it wasn't sfc /scannow, anyway downloaded the .NET 4 software, then as I say, Microsoft asked if they could take control, after 10 years of messing with computer, I think I am quite savvy, so gave in reluctantly, but it was worth it.
I remember the remote person (Arun from Banglodore, new his stuff) setup a new administrator, then loaded the disc there on uknown administrator part of the computer, when it loaded it perfectly, went back to my computer, what I'm trying to say is give them a ring. After 2 minutes on the phone, I was told it would take 30+ minutes, I informed him that this was an expensive call (at national rate) me from the UK, and him in India, he fully understood, and rang me back...............excellent service from all at the service department, couldn't do enough for me. Hope this helps:)

Problem solved!

I reset the system, with F9 at starting.

Sinok, I am having massive problems and need help - could you please elaborate on what you mean by you reset your system? do you mean you reinstalled the OS??
Thanks!
