Windows 7: Error 1935 - impossible to install Office 2010

Error 1935 - impossible to install Office 2010

I had Office 2007 running fine on my Win 7 x64 machine, don't ask me why I decided to waste my time to uninstall it and try to install Office 2010... Get the error 1935 bla bla.... for about 20 trials to install.

Tried all the rounds suggested: .NET repair, system restore now no longer complete (no change to system), no matter which restore point I choose..., disble Anti-virus (Kaspersky), try to install in Safe mode, I probably forget half of the list I have tried... Always same result. Worse: I get the same thing if I try simply to reinstall Office 2007!

I get that (no details needed - I see this had been a classic for at least 5 years now with no effective solution but to reinstall Win 7 or Repair - even though I have read the latest sometimes did not even worked). Both are out of my options: this machine run much more important programs/projects (recording studio, video editing) for fooling around with reinstalling. Plus, I have a OEM install and paid for online purchase of upgrade to Win 7 Pro. So even repair in these conditions is not possible from what I read.

I have not read anything new written since early 2010 on this topic, is there anything new to solve it? It appears MS have not been able to solve this for 6 years, and 3 versions ! I had same problem last year with Expression Web 2 and 4, finally been able to solve with 4 after a system restore. I was hoping to do the same here.

I'm now left with the unpractical option of doing all my Office work on my laptop. Funny enough: I have a Mac version of Office 2011 on a Mac and it run soooo smoothly. Even more funny: I *only* have this install problem with MS products, no other *non-MS* programs!... Unless someone has the miracle solution for this.

The following Microsoft Article about this error was updated at the end of August 2011:
Error message when you try to install an Office program: "Error 1935. An error occurred during the installation of assembly component"

It certainly appears that they think it is related to .NET framework installations. Perhaps it would be worth systematically trying the resolution(s) suggested.

Please let us know if you achieve any results.

.NET 4 ... Do I also (really) need .NET 1 ??

Hi Irene,
This page still stick to .NET 1 or 1.1 then 2... I do have .NET 4 in the installed programs (from what I see in C Panel). Does this means I should *really* install .NET 1 (or whatever low digit they refer ?) This also stick to Windows Server 2003, Windows XP, and Vista - no mention to Win 7 (so I wonder if the date simply update automatcally, or if it was just reconfirmed there without any update - you would read exactely the same thing in older versions of the answer...)

But this really makes me wonder: *can* or *should* I install .NET lower version ... to get Office **2010** on Windows 7 install ?

  • Microsoft Office Basic 2007
  • Microsoft Office Enterprise 2007
  • Microsoft Office Home and Student 2007
  • Microsoft Office Professional 2007
  • Microsoft Office Professional Plus 2007
  • Microsoft Office Standard 2007
  • Microsoft Office Ultimate 2007
  • Microsoft Office Access 2007
  • Microsoft Office Excel 2007
  • Microsoft Office InfoPath 2007

  • Microsoft Office Professional 2010
  • Microsoft Office Professional Plus 2010
  • Microsoft Office Professional Plus 2010 Home Use Program
  • Microsoft Office Standard 2010
  • Microsoft Office Starter 2010
I am not a .NET expert, but if I were in your position, I would simply follow the instructions in the MS Article and see what the outcome brings.

Should it not resolve the problem, you could perhaps checkout the MS Online Support:
