Getting the VS fortran integration to recognise a slightly older compiler version

[IanH]

Due to an ice or two I've been playing compiler version hopscotch. Subsequently the integration in VS2005 and VS2010 (both professional editions) only acknowledges 12.1.1 as the available compiler version, but the machine also has 12.0.5 installed (programs and features tells me this, plus I can compile with that version from the relevant command prompt). Is there a way that I can give the 12.1.1 fortran integration a nudge to get it to acknowledge its older sibling?

More detailed history - the machine was solely 12.1.1 (upgrades had replaced previous versions), then I installed 12.1.0 alongside, then 12.0.5 alongside, then I think I noticed that the integration wasn't acknowledging 12.1.x, uninstalled 12.1.0 and 12.1.1 and reinstalled 12.1.1. Some previous installs may have been of the "fortran suite, IA32 and Intel 64" variety, but for the recent hopscotch I'm just using the no shell IA32 compiler only packages (Is this lack of consistency in the package capability causing my problems?).

Thanks in advance for any advice (or alternatively, for releasing update 8/12.2 real pronto...)

Uninstall and reinstall 12.0. This should do what you want.

Thanks. Just tried that - but now 12.1.1 is missing from the list in the integration, despite still being installed according to the operating system and command line tests.

I'll uninstall all ifort versions and other Fortran suite stuff and try again from scratch in release order, using consistent packages.

Make sure you choose the option to have side-by-side installs and not the "upgrade", where the newer one replaces the older one.
