TextPipe use of jscript.dll ?

jscript.dll zero day microsoft
Having read of the recently reported zero day vulnerability of jscript.dll in Windows,
and the fact that Microsoft has described only a mitigation workaround for Windows 7 users after extended support ended in January 2020,
it occurs to me that as TextPipe has a special filter for running JScript language,
to ask whether this uses the vulnerable jscript.dll or the non-vulnerable jscript9.dll ?

If the latter, there should be no serious consequences.

If the former, it would likely be the case that Windows 7 users that implemented the Microsoft workaround
may encounter unexpected issues when seeking to use a filter that runs JScript.

If this were the case, then TextPipe ought to be updated to use jscript9.dll and not jscript.dll

Hi David,

We don't directly call any jscript DLL by name. We call it by its COM registration name, which will be the patched or unpatched DLL as the case may be,
