This is the Police Message Board  

Just to make sure, you are using "this is the police" and not "this is the police 2" with the corresponding trainer right?

Hah yeah, This is the police (1) and the appropriate trainer

Thank you for the game exe, it's identical to mine. I played the game and used our trainer without a problem.

Is this the only trainer from us you currently have an issue with? When exactly do you get the error notification? Have you checked your .NET Framework installation (Link)?

Weird, not sure what to do. Yes, this is the only trainer with the issue. I have several others that work fine and just double checked them. It happens when I activate the trainer (F1), it says "Please wait" and then a few seconds later "Error"

I tried the .NET link, when I open that it's a repair tool of sorts that says it's fixed any errors and to try installing .NET again - I do that and it says it's already installed and won't go any further.

Please check if any of your other trainers is also written by 0x90.

And if you like to run this here on your OS -> Link as described.

I'm running the checks now on my system (Windows 10 Pro 64)

I have one other by 0x90 that works fine for Frostpunk.

Did the suggested checkups and everything's fine with windows

That must have fixed something, it works now! Sorry for all the hassle and thanks for the help.
