Windows Vista, Win7: Emulator does not start.

Lets check the possible reasons if hardware key emulator (virtualization software) does not start.

1. You try to use 32-bit solution on the 64-bit system or vise versa.
2. Emulator system driver does not have a valid signature
3. Emulator requires extra license
4. You do not have Administrator privileges
5. Anti-VM or Anti-Debugger protection

Problem 1 symptoms are
 * devcon.exe tool shows 'devcon failed' error during the installation
 * In the "Device manager" - "System devices" you can find 'Unknown device'

Problem 2 symptoms are
 * After a solution installation virtual device has status 'Error 37' or 'Error 39' or 'Error 52'
