From the release notes:
"Install into a new empty directory. Installing on top of previously installed
builds may cause problems."

I tried uninstalling 1.3.1 then running the 1.4rc2 installer.  Same effect.

> I tried uninstalling 1.3.1 then running the 1.4rc2 installer.

but was the directory actually empty after the uninstall?

Comment 4

[Stephen Glow]

That was the problem.  The uninstaller didn't remove the spell check & one
plugin (NPSWF32.dll).  After removing those the install of 1.4rc2 went smoothly.

Sorry about that (no doubt this is a FAQ).
