Scott Cantor commented on SSPCPP-406:
-------------------------------------

You're probably right, I didn't think much about it.

I don't think you can install them both at once right now, though I suppose it could be possible with some work.

> The msi installer checks to see whether each previous version has been installed, and throws a "Please uninstall first" message out if it finds one.
> By inspection of the MSI the x64 installer only checks against x64 installs and the i386 installer only checks against i386.
> Checking may in fact become tricky since the x32 installer will be running inside WOW32 and seeing a virtualized registry.  Indeed there may be reasons why the masochistic would want both versions installed.  In which case this can be closed as mistaken.
