Error 1935 or 2908 when installing Office 2010 - here is the solution!

Glad to know that you fixed the issue and thank you for sharing the solution with us. It will help other community users in a great way.

I'm also getting this error but installing the latest .NET doesn't fix it for me.

Here's the background:

- Installed Win7 x64 on a new machine

- Installed Office 2010 Plus

- Installed a couple of other apps I needed

- Ran flawlessly for 2 days

- Came to work one morning and PC wouldn't boot to Windows.  Investigation showed the registry was corruptted somehow.

- Restored to an earlier version and everything booted fine.

- Reinstalled all the apps that disappeared (Except Office)

- Worked flawlessly for a week

- Needed Office, found it wasn't there so reinstalled, install failed with error 2908.

Since then I've tried to install it quite a few times.  I ran a "Fix It" for Office 2010 that I found on a knowledgebase article on microsoft.com that referenced a similar problem.  I've ensured that Office is not installed.  Office is not in the registry under HKLM/Software/Microsoft or HKLU/Software/Microsoft. Latest .NET is installed.

Can anyone else offer any other advice?  I'd prefer not to have to reinstall everything from scratch...

I tried this plus Windows Safe mode start up as recommended by someone else and nothing has worked.

Microsoft techs are telling me to reinstall Windows 7 OS (which came with my desktop - I do not have an installation disk - only System Recovery) but I will loose all of my work previously created with Office 2007 (which no longer works either as a Microsoft Tech deleted it from my computer when he was trying to install Office 2010.) HELP and thanks so much.

Wow, thanks RayCooper! I was having the same problem with error 1935 trying to install Office Home & Student 2010 on Windows 7 Home Premium x64 system. I tried everything and spent two days working on this thing. TrustedInstaller was missing from the system and I copied from another computer using the steps above. Once the service was started I retried installing Office 2010 and it completed finally. Microsoft was no help to the end user who called for support. Installation failed with assembly component {89EDD3A9-944B-3257-8484-D6EB6A00DDF5} HRESULT: 0x8007002.  Hope this helps someone else with the same problem.

I have exactly the same problem: I am not able to install office 2010 on a windows 7 machine x64 and I spent already many hours working on this issue....

I am also missing the trusted installer (C:\Windows\servicing\TrustedInstaller.exe), where can I get it?

Thanks.

I just got Office 2010 today.  I get the same pair of errors.  2908 that stopped the installation, then 1935 after the rollback is done.

I have the Trusted Installer file.  I uninstalled the .NET, rebooted, reinstalled .NET, rebooted, and still get these errors.

I have Win7, 64-bit.  Anything else I can try?

Oh ____, I can't even get Office 2007 back on my PC! I get same error!  I need Word and Excel for my classes!  Why can't MS stuff work like it should!

Help!

I have Win7 64-bit, and avast antivirus. I previously was successfuly using Office 2010 Beta, but was told it needed to be uninstalled as it was expiring and to install Office 2010. Now i get the error 1935 Installation failed with assembly component {89EDD3A9-944B-3257-8484-D6EB6A00DDF5} HRESULT: 0x8007002. 

I see that i no longer have the Trusted Installer.exe on my laptop.

I have tried to uninstall and reinstall .Net Framework 4.

I am not interested in completely reinstalling Windows, i dont see why i have to put up with such an inconvenience if the office beta 2010 was running on my computer fine.

What steps can i take to fix this issue and install office 2010? Is there any way of obtaining trusted installer.exe?

 

I just want to install office 2010, help.

 

 

I just had a 4 hour interaction with Microsoft support and we failed to install MS Office 2010.THe advice provided was to find the reinstallation disk of Win 7 and take it from there.

I am not satisfied with that solution, it presents a lot of downtime given all teh backing up. What i don't understand is that if people are able to find copies of a "Trusted Installer" file and then sort themselves out with the uninstall and reinstalling of the .net framework 4.0, then why can't microsoft provide a patch of some kind that deals with the trusted installer issue more seamlessly?

Given my starting point was a reasonably smooth PC that was running MS Office 2010 Beta, i find this to be a real let down.

Sorry but neither of these links was successful for my problem. I tried to download each of the links and they both failed and rolled back.

I tried to reset my entire brandnew laptop only 3 days old incase any of the windows office programs that I had uninstalled in preparation for installing Office 2010 were needed to facilitate the loading of Office 2010. Even trying to reset the system only succeeded in removing a few non-essential programs I had downloaded from the web. It did NOT reinstall the various microsoft files/programs etc that i had uninstalled on the first day. I have tried almost every suggestion shown in this forum and STILL nothing! I believe I still have the Trustedinstaller.exe needed.

My next question...should I turn of the security program while trying to install Office 2010? It seems silly but I am open to all possiblities at this point. Like most of the others here I have tried this at least 7 times now and am fast loosing patience!!!
