Adobe – Error 1935. An error occurred during the installation of assembly component

I updated Operating system to Windows 7. While installing Adobe Reader X (10.1.1) on Windows 7 I received following error.

Error 1935. An error occurred during the installation of assembly component {B708EB72-AA82-3EB7-8BB0-D845BA35C93D}. HRESULT: 0x80070BC9

This is very strange, I’ve never seen any Adobe Reader installation error in the past.

At first I thought it might be due to the user permission issue. In next attempt I tried to run the Adobe Reader installer as administrator.

Adobe Reader Installation Error - Error-1935
Adobe Reader Installation Error – Error-1935

To run Adobe Reader installer as Administrator, right click on the installer and select Run as administrator.

Run Adobe Reader Installer as Administrator
Run Adobe Reader Installer as Administrator

However this didn’t solve the problem.

Finally I did some search and found the solution.

The solution is to disable all startup items (and services) and then install Adobe software.

Updated: As mentioned by JB below in comments if you have Windows updates to be installed then let them install first and try to install Adobe software. If this doesn’t solve problem then proceed with following  solution.

How to disable startup items and services?

1. Close all application

2. Launch System Configuration utility.

Windows key+R

Type msconfig and hit Enter key

msconfig - Start System Configuration Utility
msconfig – Start System Configuration Utility

3. In the System Configuration window, click on Startup tab

4. Uncheck all the Startup items which are checked. Note down the items which you have unchecked as you will need to check them again after installation.

5. Click on Apply, OK and restart Windows.

6. On Adobe site they have suggested to stop all the services tool. I didn’t do it. For me just disabling Startup items worked. If disabling Startup items doesn’t work for you then in next attempt you can disable the Services too.

7. Once Windows start, disable any services which are started. No need to restart Windows.

Run the Adobe Reader Installer as Administrator. Running as Administrator might not needed and you can run as normal user. If you get any permission related error then you can run the installer as Administrator.

That’s it.

If you are using any other operating system such as Windows Vista, Windows XP etc then you might try above method or refer to Adobe site for help.

This error is not limited to Adobe Reader only, you might get the same error for other Adobe products.

I saw this error when I was installing Adobe Acrobat Pro X. However I didn’t see this error during installation of Photoshop, Dreamweaver or Flash applications.

Total Time Waste: About an hour.

People to Blame: Adobe and/or Microsoft.

  1. I refuse to modify my Windows setup just because Adobe cannot write a decent installer? If I have to do such tricks, I switch to Linux.

    1. Only if Adobe and Microsoft software were as simple as Linux’s applications.

      It doesn’t take more than 2-3 minutes to change the start up options and revert it back. Choice is yours.

    thnx bro, it works

  5. thank you very much for the very useful report

  6. thanks a lot. This error occured with me after installing Adobe Reader X package. Simple unchecking of the start up items did the miracle and the reader is properly installed now.

  7. You are a genius. I was ready to tear my hair out before I stumbled upon your article. Thank you so much.

  8. Thanks – you put me on the right track – but in my case the problem seemed to be that Windows was waiting to configure updates. Once that was done it worked anyway. As ever, though, you’d think they’d SAY that …

    1. Thanks for mentioning one more reason. I’ll add this in my list.
