"Silverlight control has NO elevated security privileges "

SA-5796

Summary



I'm trying to implement Word Document generation under Pega 7.1.7.

First, I tried it via Designer Studio / Process and Rules / Case Management / Gallery

There is "Create Word document" example.


Error Messages



There are two messages:
1.
SilverLight Installation Required

PRPC Silverlight prerequisites are not installed. An automatic installation attempt is now being started. If the automatic installation fails, you must manually download and install SilverLight.cab to use this feature. Click the link below, extract the files, and run setup.exe from it. You will need to restart all instances of your web browser after this is completed.

2. "SilverLight Control ERROR in 'LaunchWordMerge': Aborting Word Merge launch. Silverlight control has NO elevated security privileges on the client workstation."


Steps to Reproduce



Go to Designer studio.
Open Case management gallery (via "Designer Studio / Process and Rules / Case Management / Gallery").
Launch "Create word document".
Click "Preview" button.
Click "Create Merge Document".


Root Cause



Both registry “AllowLaunchOfElevatedTrustApps” andAllowElevatedTrustAppsInBrowser” need to be set to 0x00000001 (enabled) to allow Silverlight to run

.

Resolution



The root cause of this problem is defect/misconfiguration in the PRPC operating environment.
This issue is resolved through the following local change:
Set both registry “AllowLaunchOfElevatedTrustApps” andAllowElevatedTrustAppsInBrowser” to 0x00000001 (enabled) to allow Silverlight to run
