Installing ArcView on Windows Vista or Windows 7 has a problem of compatibility. Forcing to install it will comes to error message windows such as the following image.

This program can not be installed on a Windows 3.5.1 operating system
That is caused by incompatibility between Windows Vista/7 with ArcView platform. To get out of that problem, we need to set the compatibility of ArcView 3.x installer file as follow.
- Find the installer file of ArcView 3.x (setup.exe)
- Right click on setup.exe file

- Select COMPATIBILITY tab
- Tick on ‘Run this program in compatibility mode for:’
- Select what OS compatibility for. For example Windows XP (Service Pack 3)

- We may need to Tick on RUN THIS PROGRAM AS AN ADMINISTRATOR
- Click OK to conform and close the window
- DONE
Next, we can install ArcView 3.x as the same as we install it on Windows XP. Enjoy.
