BAR CODE FONT IN WINDOWS 7 Ultimate 32 bit

Sir,

I have been using Bar Code Fonts viz. IDAutomation,Code128 in Crystal Reports without any problem in Windows XP using VB6.

But in Windows 7 Ultimate 32-bit,Bar Code Font is displaying not properly,is displaying just odd lines.Otherwise MS Word document is showing Bar Code font on any text correctly,but not in Crystal Reports


Any answers to this query would be highly appreciated.


Thanks,
