If you want to install both GOWrite versions, you should note following:
In Windows only one program can be associated with file extension SGF. Thus either GOWrite 1.4 or GOWrite 2 will be used when opening SGF files.
During both GOWrite 1.4 and 2.0 installation you have possibility to select if program should handle SGF files. Please select this only for the program you want to use for opening SGF files.
GOWrite 2 can use alternative (private) extensions GW2 for files. This allows one to use GOWrite 2 even if some other program is handling SGF files. In order to make extension GW2 default, please go to Options -> General Settings dialog in GOWrite 2 and select GW2 as default extension.
Installation: Installing both 1.4 and 2.0 GOWrite versions
