Description: Uninstall v8.0 removes files v8 Beta4 is
dependant on.
Details:

I installed release v8.0 in a seperate directory from my beta4
installation
and then uninstalled it. This removed at least one of the
shared files the
beta was dependant on. When I try to start the beta as a service I get
"pg_ctl.exe - Unable To Locate DLL" pop-up with the following
information:

The dynamic link library libpq.dll coud not be found in the
specified path
C:\Tools\PostgreSQL\8.0.0-beta4\bin;C:\WINNT;... (etc., rest
of the path
deleted).

I know I should not speculate, but there is some risk that someone will
install the release and then uninstall a beta (after
configuring and testing
the release) and break the release installation.

Was beta4 installed by the MSI installer? It's really supposed to take
care of that. libpq.dll should be in SYSTEM32, and shouldn't be removed
until *all* instances are uninstalled. I have tested this several times,
and it has always worked in my tests.

Do you ahve any other software installed that may have provided a
libpq.dll`?
