Those pre-release installers are identical to the rw1020 one.

rwinst.exe uses most of the standard system dlls, plus msvcrt.dll.
pedump will show you exactly. But I suspect the problem is more
prosaic, in that you have an exceptionally long (or in some other way
The only differences between rwinst for rw1011 and rw1020 are
1) It is compiled against msvcrt.dll.
2) When that radio button is clicked for the first time it
i) Checks if R_HOME is set
ii) if not, looks for ...\rw1020\bin in the PATH
Now, this works for me on several machines and on several OSs (98/NT/W2K)
with and without R_HOME set and/or ...\rw1020\bin in the path. Try
setting R_HOME and see if this cures it. If so, my guess is that that the
PATH is malformed (for example, it might exceed the supposed maximum path
length, which my experiments just now suggest is possible).
If setting R_HOME solves the problem, please try a new version I've put at
which differs only in not looking at the PATH at all.
