Yup, that's right, Quickbooks pro 98. I currently have it installed on Windows 7 pro and it seems to be fine with no problems what so ever. After calling Intuit and having two CSR ask what ver. trying not to laught, they said it won't work and I could loose all my company info. Does anyone have any input what so ever on this. I picked the copy up for free, I really like that price point, but want to make sure I'm not going to run into something I haven't seen yet. If it is known to be problematic, can I upgrade to Simplestart 2006and keep all my company info or would I have to reenter everything again? Thanks for any info you can give!
