            Status: UNCONFIRMED
          Severity: normal

Steps to reproduce the problem.

SETUP:
    Ubuntu 10.10 Maverick Meerkat
    wine-1.3.13
    winetricks 20110123

PROBLEM:

After using "winetricks directx9" users may see the following error message
whenever they start a wine application:
    The program mscorsvw.exe has encountered a serious problem
    and needs to close. We are sorry for the inconvenience.

The started application is (usually) unaffected.

CAUSE:

The last couple of lines of winetricks' load_directx9() function are:
    # reenable mscoree, or other installs may fail, see issue 25
    w_override_dlls builtin,native mscoree

Doing this, however, clobbers mscoree as used by .NET Framework 2.0. Whenever
you try to start Wine (even for something like wine regedit) the ".NET Runtime
Optimization Service v2.0.50727_X86" service fails to start with the following
error message:
    The program mscorsvw.exe has encountered a serious problem
    and needs to close. We are sorry for the inconvenience.

WORKAROUND:

Start winecfg, go to the Libraries tab and change the override from "*mscoree
(builtin, native)" to "*mscoree (native)". The error message goes away.

REPRODUCING:
