Installation Error 1935 Follow


When trying to install a Palo Alto Software program, you may got a message like the following:

"1935: An error has occurred during the installation of assembly component.... Microsoft.MSXML2, public Key Token =...."

Why is this happening?

A Microsoft update you recently received has been only partially installed, so the Windows Installer cannot provide the proper version information needed by our software to complete the installation.



Take the following steps to manually update the Microsoft XML files on your computer in order to resolve the error:

First, download the MSXML4 Sp2 update

  1. Click the following link to open the related Microsoft Article: MSXML 4.0 Service Pack 2 (Microsoft XML Core Services)
  2. At the bottom of the article, click the "Download" link for the msxml.msi file, and save the file to the Desktop of your computer.

Then, remove the partially installed software

Once the update file has been downloaded to the Desktop of your computer, take the following steps to remove the partial installation of the Palo Alto Software program from your computer:

  1. Close any open programs.
  2. Click the Windows Start button, point to Settings,and click Control Panel
  3. Double-click Add/Remove Programs.
  4. Select the Palo Alto Software program (if present) listed by its name and clickRemove. (example: Business Plan Pro 2004)
  5. From the same list, select Application Manager (or Palo Alto Software's Application Manager) if present, then click Remove.
  6. Once finished, restart the computer.

Now, clean boot the operating system

You may want to print these instructions out before continuing, as they require restarting your computer.

Note: You must be logged on as an administrator or a member of the Administrators group to follow these steps. If your computer is connected to a network, network policy settings may also prevent you from follow these steps.

  1. Click Start, click Run
  2. Type msconfig in the Open box, and then click OK
  3. The System Configuration Utility dialog opens
  4. On the General tab, click Diagnostic Startup
  5. On the Services tab, click the word "Service" at the top of the list to alphabetize the services
  6. Locate and check the box for Windows Installer
  7. Click OK, and then click Restart to restart your computer.
  8. Once the computer has restarted, click OK to the message about the System Configuration Utility
  9. Close the System Configuration Utility by clicking Cancel.

Install the Microsoft update

On your Desktop, double-click on the msxml.msi file which was downloaded from Microsoft's Article to install the Service Pack 2 update for the MSXML components of Windows.

NOTE: If you encounter an error when attempting to install the update, you may have to remove the previous versions of MSXML before continuing. Detailed instructions:

Return to normal mode and install the software

  1. Click Start, click Run
  2. Type msconfig in the Open box, and then click OK
  3. On the General tab, click Normal Startup
  4. Insert the Palo Alto Software CD-ROM (or click the downloaded setup files) and install your software.

Additional Detail

The 1935 Error message is generated by the Windows Installer when it is unable to access a specific file, folder, or area of the system's registry for some reason. Normally, this error is generated if the user does not have full administrative rights to the entire computer (including all files, folders, and areas of the Windows Registry). 

In this situation, the 1935 error appears to be related to some recent updates released by Microsoft for the Microsoft XML Parser. One of these updates is partially installed on the computer and the Windows Installer is unable to verify and provide the proper version information to our Installer Package. This failure generates the 1935 error message when our Installer is unable to determine the version of MSXML installed on the computer.
