Fix: An Error Occurred During the Installation of Assembly Component

by

I was recently installing Microsoft Office 2010 on a Windows XP computer when I encountered an error. The error prevented the installation from continuing, which prevented Office 2010 from installing. Installation errors can be a pain, as some error messages may not be well documented. Luckily, Microsoft OFfice 2010, much like all version of Office since 2000, use the Windows Installer service for installation.

While the error itself doesn’t provide a whole lot of information regarding the problem, a quick search yielded the solution, which I outline below.

Microsoft Office 2010 Installation Error 1935

As mentioned I received an error when attempting to install Microsoft Office 2010 on a Windows XP computer. The error I received was:

Error 1935. An error occurred during the installation of assembly component {10CD20D2-733E-4174-9D02-2C6C26163DA5}.

After doing a a quick search I found out that the error is related to the .Net framework that was installed on the Windows XP machine. Depending on the version of the .Net framework that is installed, there are actually to methods of solving the problem.

.Net Framework 2.0 Installed

In my case, the .Net framework 2.0 version was installed on the Windows XP computer, so all I had to do was repair the framework to correct the problem. To repair the framework, I used the following steps.

  1. I clicked “Start->Run”.
  2. When the Run dialog appeared, I typed “appwiz.cpl” and then clicked the “OK” button.
  3. In the “Currently installed programs” list, I clicked “Microsoft .Net Framework 2.0”, and then clicked the “Change/Remove” button.
  4. When the setup window was displayed, I selected “Repair” and then the “Next” button.
  5. The .Net framework was repaired and the Office 2010 installed completed successfully.

After correcting the above error, I update the .Net Framework to version 4.0 to avoid any similar problems in the future.

.Net Framework 1.1 or No Framework Installed

Unlike current version of Windows (Vista and 7), Windows XP didn’t include the .Net framework, which was installed once Windows update was run. For those with .Net framework 1.1 installed, or no .Net framework installed, you should update to .Net framework 4.0 to correct the issue.

You can use the “Windows Update” tool to update to the .Net framework to version 4.0, or use Microsoft .NET Framework 4 Web Installer to update.

In the end, the .Net framework caused the installation problem, which was easily solved by repairing the framework that was installed on the Windows XP computer.
