Environment
Situation
When attempting to install Microsoft Silverlight 2 (Silverlight.2.0.exe available from http://www.microsoft.com/silverlight/ effective October 2008, a plug-in for multimedia web applications) on a system that already has INFOConnect installed, you may see an INFOConnect Installation dialog prompting for a package location.
Figure 1. INFOConnect Installation dialog: 'Insert package DISK 1 or Enter package root directory.'
Silverlight is not able to install. Clicking OK re-prompts for a location; clicking Cancel closes the installation.
Similar symptoms are also known to occur with some applications from other vendors that use the install.exe file name.
Resolution
Option B: Extract and Run Silverlight Install.exe
Option C: Modify the Registry
Option A: Upgrade to INFOConnect 9.0
INFOConnect Enterprise Edition version 9.0 uses different installer technology, and this Silverlight problem does not occur. If you have a current maintenance plan for INFOConnect, download the latest version at https://download.attachmate.com/upgrades. For information on new features in version 9.0, see https://docs.attachmate.com/infoconnect/ented/9.0/pdf_docs_infoconnect/release_notes_infoconnect_v90.pdf.
After INFOConnect version 9.0 is installed, proceed to install SIlverlight 2.
Option B: Extract and Run Silverlight Install.exe
The problem does not occur when you manually extract and run the Silverlight installer. Follow the steps below to extract Silverlight install.exe and successfully complete its installation.
- When downloading Silverlight.2.0.exe, click Save instead of Run. Save the download file to a temporary location, such as your Desktop or C:\TEMP. Note: Do not click Run in the web browser before or after downloading.
