Cheat Engine

Viloresi

Hello I'm trying to use cheat engine 6.7 on:
Windows 10
Version 1903 (build SO 18362.267)

last updated today (1 august 2019)

unfortunately it keeps BSOD when I try to enable DBVM by clicking on Help-> About-> "Your system supports DBVM" .
With cheat engine 6.8.3 I don't have any problem, dbk64.sys loads correctly and I'm able to start DBVM, also I didn't use the version 6.7 for a long time (likely 2 years) but now I need to use that

important thing when it comes to DBVM is the cpu you use. AMD's are currently not functional with DBVM

Also what BSOD do you have ?

watchdog timeout is dbvm freezing on a state it doesn't recognize.

Make sure no other hypervisor is running at the time (no vmware running, no hyper-V)

there shouldn't be a hypervisor running, I don't have vmware and hyper-v installed anyway I'm having this problem only with CE 6.7 , not with 6.8.3 sorry for my lack but the cheat engine driver is similar it should work on both right?

6.8.3 is very different from 6.7.
e.g 6.7 dbvm can not be loaded by 6.8.3 driver and same the other way around (you'll crash)

but what you can do is load dbvm with 6.8.3 and then close ce and run the kernelmodule unloader

then try 6.7

also why do you wish to use 6.7 ? it has many bugs and doesn't even have cloaking support and invisible find what access breakpoints

The driver that comes with CE releases won't talk to modified CE versions. You need to compile the driver yourself and boot windows in testsigning mode, or sign it yourself with EV codesigning certificate

and forceload only works on windows 7

But wht you could do in 6.8.3 is hook the windows kernel functions that are used for detecting CE. E.g openprocess, readmemory, window caption enum

alright I've made a mistake, I should've used cheat engine 6.7 (official) to do the test lol... anyway I've decided to use the 7.0 beta and leave the 6.7!
Thank you anyway your answers are always helpful.
I'm gonna explore the new functionalities too
