Bug ID: 40186
           Summary: mscoree:mscoree test regression
           Product: Wine
           Version: 1.9.3
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mscoree
          Assignee: [e-mail]
          Reporter: [e-mail]

The commit below causes the mscoree:mscoree test to crash on several Windows
VMs:
* wxppro-sp4v3.1a (Windows XP SP3, latest installed .net runtime v2.0.50727)
* win7u64: All the versions with .Net 2.0.50727, which is all of them except
the one with no service pack (-0sp).

The crash happens after these traces:
mscoree.c:108: latest installed .net runtime: L"v2.0.50727"
mscoree.c:129: latest installed .net installed in directory:
L"C:\Windows\Microsoft.NET\Framework\v2.0.50727\"
mscoree.c:137:  installed in directory
L"C:\Windows\Microsoft.NET\Framework\" is .net version L"v2.0.50727"
mscoree.c:431: Tests skipped: .NET 4 not installed.
mscoree.c:453: Test failed: CLRCreateInstance failed, hr=0x80004001
mscoree.c:453: this is the last test seen before the exception
mscoree: unhandled exception c0000005 at 0040414A
test failed: crash

So most likely when the tests tries to use metahost after the failed
CLRCreateInstance(&CLSID_CLRMetaHost...) call.

Obviously the test should (win_)skip these tests if there is no suitable .Net
runtime so as not to cause failures or a crash.
