If you encounter the error "Error: 2738.Could not access VBScript run time for Custom action" during installation of Ignite, you will first need to register the vbscript.dll. To register it, bring up a Command Window, at the prompt enter the following commands:
cd %windir%\system32
regsvr32 vbscript.dll
After the vbscript.dll is successfully registered, rerun Ignite's Installation again.
