Change/Set OS version like the ols SetVer.Exe program

I have an application that was written back in the
Windows 95 days and it uses InstallShield to install.
It looks for min OS of Win 95 or NT 3.51. Trying to
load on an XP machine, is does not know or recongize
XP so it won;t install. This there a workaround for this
like how we used to use setver.exe for DOS programs????
