Environment

INFOConnect Enterprise Edition version 7.5 through 8.1 SP2

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

To install Silverlight 2 on a system with INFOConnect already installed, use one of the following solution options.

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.

  1. 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.

Option C: Modify the Registry

The Silverlight 2 install problem can be resolved by removing two INFOConnect values from the App Paths\install.exe registry key. Removing these registry values does not affect the performance of INFOConnect, including installation and uninstallation.

Note: Proceed with extreme caution when editing the Windows Registry. For full details and warnings regarding editing the Windows Registry, see Microsoft Article 256986 at http://support.microsoft.com/default.aspx?scid=kb;en-us;256986.

Follow these steps to modify the registry:
