 you've got to do it every time. the needed msvcr70.dll & similar are al a
 carte in the downloaded tarball, and get installed to C:\Program
 Files\GRASS...\extralib, so are install specific, & need to be done for
 each time, for each version. AFAIK only the 2010.exe installer puts the
 msvcr100.dlls in C:\windows\system32 and so survives. I don't know what
 the 2005.exe and 2008.exe installers actually install (but I'd like to).

 So the three ms-$year.exe installers run, but also a number of dlls are in
 the tarball and copied separately. The three ms-$year installers should
 survive reinstall, but don't provide all the Microsoft-provided libraries
 we need.

 probably(?) there is some other ms redistributable installer which
 installs the ones we need system wide, I don't know. note the 80 and 90
 msvcr dlls are still missing (see #1428), probably causing breakage once
 the fns that need them get called.

 I don't like us installing to c:\windows\system32, I'd rather have ms's
 installers do that with their full checks, registry registration, and
 inside knowledge.

 (nope, every time)

 mmph. I don't think we can or should make it mandatory, but we might be
 able to change the default on the download page to ticked instead of
 unticked.

 I'm pretty sure it will be #1428.


 another idea is to have a tiny sacrificial osgeo4w program that runs with
 a dependency on all dlls used by the core osgeo4w toolchain, and catch the
 result so at least there is a nice error message telling you what to do
 instead of the not very helpful vanishing box. Who c/would write it? no
 idea.
