Customer solutions:

Solution 1:


The first attempt:
Still have problems with smartkey.exe

i installed it on win7 ultimate 64 bit and everything works as it should, but cann’t get it to work on xp sp3 32bit, installed the xp fresh and the ak500+ software when it starts doesn’t even search for the hardware.. but smartkey.exe when started from installatin folder works now.. The main window pops right up and only firmware update is availible. Drivers are correctly installed and in device manager is also everything ok, tried com 1, 2 and 3.. same

Second attempt:

I struggleed with this issue for a quite of time. Ok you can make a few things here. A forum member helped me to solve that. I had to use win xp SP2, and he sent me the software for ak500, not ak500+ !! The installation is different and when you install the ak500 software it adds some files wicj the ak500+ install didn’t. So after that smartkey.exe did work and when i started ak500+ also. So it was something missing in the install that i got with my device. BUT i figure it out that i need smartkey.exe ONLY for writeing the nec in the zif socket. But what i did not try and what sure has to work also without smartkey.exe was soldering the virginised nec on the key pcb and write the key via IR port !

So try that mate but the install of the old ak500 software should solve your issue.

(If you need the old AK500 software, please contact your dealer)


Solution 2:

Install fresh xpsp3 black edition, apply all patches of this xp, install ak500 software, install drivers and smartkey will work.


Solution 3:

All Ak400 and Ak500 software work, but

1. SmartKey program start only on IDE hdd, no any other work!
2. have problem with comport some time not found, this come after clear driver installation
3. for ak500 ESL 203 use any drive (local, usb) but Volume must be AK500
