I have 14 downloads of CS 777 on my computer - all uninstalled, as my computer crashed and Win 7 had to be re-installed, etc., etc...

They are:-
csx770_0100.exe,
csx772_0200.exe,
csx772_0201.exe,
csx772_0300.exe - csx772_1200.exe,
csx773_1200.exe and
csx774_1200.exe.

Can I download and install v. 1.6 after installing just csx774_1200.exe or do I have to first install all the other earlier versions?

I don't know if csx774_1200.exe is v.4, which is said to be necessary in order to upgrade to v.1.6.

Any help would be much appreciated!
