Issue
Vista WebApps install incorrectly claiming that IIS is not installed
Environment
Windows IIS
Cause
On some custom configurations of Windows we have seen where Internet Information Services (IIS) is running on another driver letter and Vista WebApps is not finding the IIS operating directory and claiming that IIS is not installed.
Resolution
- Open the Registry Editor (Start > Run > regedit)
- Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\InetStp\ for the PathWWWRoot key.
-
This registry key should show the directory that IIS is using for storage of the web server.
(Default is C:\inetpub\wwwroot\) - Correct the registry key with the correct path and the install should now succeed.
