1. What does 'Use Taggant System' do? I can't find it in User-Manual ?
2. when you close a project and exit VMProtect, why it takes so much time (lagging a lot)
3. the first time generate RSA Key, if you click the dropdown list '2048, 4096 bits ...' the VMProtect crashes
4. If an incorrect path specified in *.vmp but the correct file path is specified in the command line VMProtect_Con.exe, the VMProtect sill complains (It didn't report in 2.13)
5. the same project, protected by VMProtect3 cannot be registered (The COM object, using command regsvr32 to register as administrator) see below. It crashes on Windows 10 and Windows 2008 Server

Re: Questions on VMProtect 3
1. About Taggant System you can read here
3. We'll fix it in next build.
4. I don't understand what you mean. Could you provide us more detailed information?
5. Could you send us a test example that shows your problem?

Re: Questions on VMProtect 3
In your case you need to switch off the option "Memory protection" (or exclude segment ".text" from memory protection) because your DLL modifies own code:
Access violation here:
Memory protection disallows usage of VirtualProtect for regions controlled by VMProtect. Please notice that your code doesn't analyse the result of VirtualProtect and writes data into a read only region.

Re: Questions on VMProtect 3
Thank you for your hardwork!
Yes, I have tested and it seems working fine so far, and it passes all unit tests.
1. Could you delete the binaries I sent to you for debugging and testing purpose? I don't want trouble in the future because it is confidential. thanks
2. I tested with Hyper-V on, do you think it is possible to ignore machines with Hyper-V on as being in 'Virtual Machine'?
3. The hardware ID is changed with VMP3, but I still can decode the hardware ID string using previous method, am I right? could you confirm with this?
Thanks a lot!
