I'm waiting for an opinion or an idea on how I could get over this check.

Hi Hexcode, the program is checking it's File Certificate to see if changes to File, or it's doing a CRC Check of code for changes. Look for code where exe BASE loading offset is used as address to start CRC Check.

It is possible to crack the code that calls the Win Verify Trust Windows Function, as I have done this before, or you can use a Loader to Patch it in memory unless it also does a Memory CRC check.
I POSTED A LOADER on exetools ...

You can also remove the Certificate from a File, and replace it with one that contains the Cracked File CRC.

After cracking a file Certificate is XXXX !
Right Click File select properties to check Certificate.
