Autodata 3.38 WILL run on windows 8.

All you have to do is install as windows 7.

Go to microsoft website or paste Visual C++ Redistributable for Visual Studio 2012 into any search engine.

download vcredist_x64.exe for 64 bit version or

download vcredist_x86.exe for 32 bit vesrion.

install which ever version your machine is.

open start menu in windows 8 and under the search option search for command prompt.

type “cd c:\adcda2” and then "regsvr32 ChilkatCrypt2.dll" press enter.

re install autodata which will overite existing files.

if a shortcut hasn't been made on your desktop copy the one in windows ~adcda2 and paste it to your desktop.

right click on this icon goto properties and under compatibility mode run this program as windows 7.

job done.

it worked for me................. good luck.
