As the mingw installer does not allow an install only from predownloaded
packages, I copied the whole tree from a previous install over, so indeed
the entries were not there.

I moved my msys installation to c:\msys\1.0 and the MSYS mount point error
is gone. However, the installer can still not detect mingw although it is in
c:\MinGW. Is the installer case sensitive ?

I tried changing the name to lower case, but that didn't change anything.

I looked into the mingw-path.nsi, and found out that the strings the
installer looks for do not exist:

InstallLocation  <->
HKLU\Software\Microsoft\Windows\CurrentVersion\Uninstall\mingw32_is1 Ïnno
Setup:App Path"

This probably has to do with the version of the mingw installer ? 

If i add manually the HKLM key, the install continues. Is this the problem
you mentioned about the order of the checks (directory first, registry
afterwards ) ?

Thanks a lot for all the help, the installer now completes and I can start
msys to configure and make RTEMS.
