In the beginning I got some message about gecko etc. which i could not understand & skipped.
What do you suggest ?
Probably not the cause of your problem, but in general, you really should let wine install gecko etc on first run. Skipping it CAN cause problems.
Also, have you checked if the program will run under wine? (What application is it?)
And taking Jason W's response into account, consider switch to wine.tcz. It works perfectly for everything I've tried it with.
