Ticket #291 (closed defect: fixed)
cabal-install cannot re-install itself on windows
|Reported by:||duncan||Owned by:|
It fails when it gets round to actually installing the executable file. This is because in windows more than a little tricky for a program to replace its own executable file. Trying to overwrite or replace a file that is open by a process fails.
It is possible to rename the existing exe file so that the new one can be installed though that still leaves the problem of deleting the old exe file.
