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'




Problem 3 symptoms may differ and depend on the protection features.

Problem 4 symptoms are
 * devcon.exe tool shows 'devcon failed' immediately after start
 * No new devices in the "Device manager"



Problem 5 symptoms may differ and depend on the protection options.
