windows NT95 vs. windows XP home

[Qroozn]

I have made a program for work in excel 97.

And smart me bought a computer so i can do my own work at home and burn it to cd to bring it in and distribute it.

But Stupid me is getting Windows XP installed as the operating system. Is this gonna totally screw up my chances of adjusting my program?

As i say stilck in Excel 97 and work new version up in to higher you use, if 2000 or XP and KEEP the old and archive a copy just in case this means you can drop it all and go back to where you satarted only loss is time inversted and so you gain experiance..
