Size of unpacked hsrminer is about 30 megabytes, after packing with vmp it's 14 mb, because vmp doesn't pack some data sections and also due to additional own code of packer/protector.

Can you give me more info about crash so I'll try to repeat it.

1) cmd line parameters you are using

2) OS type (pro/enterprise/etc) and exact version, open cmd prompt and type winver - write OS version and build.

3) what is version of Nvidia Drivers?

4) Does fork crash if you just run it without any options?

5) Does it crash if you run it with -h or --help?

Thanks in advance.
