* EST3-Multiple EST SDU program on same computer

[guest]

Is that anywhere to install Multiple EST SDU program in different version cause want to keep the old sdu program.

You're better off using batch programs that put the appropriate sdu.ini file into the windows directory then autolaunching the sdu.exe that you desire

GREAT!

Install the each version in separate directories and change the sdu.ini from c:\windows\ directory
as follow example:
[SDU Directories]
AppDirectory03.61.00=C:\FAST\3-SDU_Ver3.61
AppDirectory03.70.00=c:\fast\3-sdu_ver3.7
AppDirectory03.72.00=C:\FAST\3-SDU_Ver3.72
AppDirectory03.73.00=C:\FAST\3-SDU_Ver3.73
IDAPIVer=2.50
Important: get changes only in "[SDU Directories]" section!!!

Partition the hard drive and dual boot the operating system with a different version on each OS. I have tried this in the same OS(win7) and it caused problems.. ended up uninstalling both versions and reinstalling 3.74

Try using a Virtual Partition Program. I am currently running a version of Windows 98SE, on an XP system, to allow me to access DOS programs. No partitioning required.
