If you are receiving the error message “Could not Access Javascript / VBScript Run time for Custom Action” (2738 Error), it is most likely due to one or more missing registry entries. The registry is a database that stores information and settings for the Windows operating system and for applications that run on Windows. Registry entries are created when you install or update a program, and they contain information such as the location of files and folders on your computer, the types of files that are associated with a program, and the settings for a program.
In order to fix this error, you will need to add the following registry keys:
HKEY_CURRENT_USER\SOFTWARE\Classes\CLSID\{ F414C260-6AC0-11CF-B6D1-00AA00BBBB58}\InprocServer32
HKEY_CLASSES_ROOT\CLSID\{ F414C260-6AC0-11CF-B6D1-00AA00BBBB58}\InprocServer32
These keys should be added to the registry with the following values:
“C:\Windows\system32\vbscript.dll”
“C:\Windows\system32\jscript.dll”
After adding these keys, you should be able to run your custom action successfully.
