Prevent Thread Bumping Modification Needed

[satlazone]

I need a modification which will work like that:
I set number of days until a thread will expire,
if there wont be any new replies to the thread within the number of days I set then the thread is expired.
if someone will try to reply to the thread then he will receive an error message saying: "the thread is expired and you are not authorized to post here".
And it doesn't matter if its the thread starter or anyone else, only if I exclude the usergroups then they will be able to reply.

Is there any modification like what I mentioned? I saw it working on an other forum and I dont think it a private modfication, I think I just didnt find it yet.

thanks in advance.

*edit*
I found exactly what I searched:
https://vborg.vbsupport.ru/showthread.php?t=82827

but where is the download link? and how can I get it working with vb 3.6.8
