Unfortunately, LabVIEW 7.1 does not support Windows 95 or 98. Although the solution above is certainly not supported by NI, you could give it a shot as a work around. Alternatively, if you had access to an earlier version of LabVIEW, you could develop in 7.1, then select File >> Save with Options and Save for a Previous Version back to 6.1, which would support both 95 and 98, and then create your app from there for your Windows 95 and 98 systems. I'm sorry that there isn't a more elegant solution for your issue. Hope this helps.
