Compatibility of MS SQL 2017 and software developed for 2008 or 2012 versions?

Question

SQL Server

There is software, the recommendations of which indicate the version of MS SQL 2008, MS SQL 2012 and higher
.
I tried to switch the database to compatibility mode https://docs.microsoft.com/ru-ru/sql/t-sql/stateme...
but it didn't work.
Apparently the software determines the server version by connection and refuses to work. The database is very simple, only 3 tables, no SQL bells and whistles are required. I contacted the developers - they promised to add support in the distant future.
The question is, is it possible to fool the software into thinking that it is running a lower version of the server?

Answer 1

We are looking for a line in the @@version application, if we do not find it, we are looking for SERVERPROPERTY. Then we find the check of the results with a debugger and kill it.
