32Bit Exe file Convert to 64Bit

[cyclone]

Hi all
I have an orginal licensed software that protected HASP dongle.
It is working 32 bit windows (either windows 8). But its not working under windows 10.
"Dongle key not found" it says under windows 10 x64.
Even then I upgrade driver files to latest. It is not working.
Is there any change to convert exe files to x64 or solve this problem.
PS : Do not say please contact the company because software is very old. And the company is gone already. (it is already bankrupt)
I do very appreciate if any one can help me.
