Error Message

When installing ArcGIS Server, ArcGIS Desktop, including ArcView, ArcEditor, ArcInfo; or ArcIMS, the following error may occur:

"Error 1935: An error occured during the installation of assembly component {303994BA-6487-47AE-AF1D-7AF6088EEBDB}. HRESULT: -2147024894."

After clicking 'OK' the installation rolls back.

Cause

This error occurs during the system update stage of the installation when the Microsoft XML Parser 4 installs. The same error should occur when trying to install the Microsoft XML Parser 4.0 by itself.

The cause can vary, but frequently may be caused by system files being used by another product.

Solution or Workaround

Follow the steps below to work around this error.

Stop as many programs as possible. Some programs may be running in the background, such as adware or spyware. An example of such software is Adwatch. If possible, remove any adware from the machine.
Stop as many Windows services as possible by navigating to Control Panel > Administrative Tools > Services.
Verify that Internet Explorer 6.0 is installed. Verify that all Microsoft service packs and updates have been installed.
Install Microsoft XML 4.0 SP2 before continuing. Download the link in the Related Information section below.

The previous XML parser may need to be uninstalled before installing XML 4.0 SP2.
Install the ESRI software again if Step 4 was successful.
