Bug ID: 47253
           Summary: Signature verification fails on wine 4.8, can't
                    install Battle.net, vcrun2010+ etc.
           Product: Wine-staging
           Version: 4.8
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

I'm running Wine Staging 4.8 on Fedora 30. In this version, several installers
that do a signature verification fail. The easiest way to reproduce is to
simply run 'winetricks vcrun2010' which will fail when trying to verify its
files.

The vcrun2010 install logs contain the following error message:

y:\de00b8bff7881faccd8cf470e51735\vc_red.cab - Signature verification for file
vc_red.cab (y:\de00b8bff7881faccd8cf470e51735\vc_red.cab) failed with error
0x800700a1 (Path is invalid.)
No FileHash provided. Cannot perform FileHash verification for vc_red.cab

A similar problem can be observed with the Blizzard Battle.net installer which
also complains that it can't verify a digital signature.

The same problem does not happen when downgrading to 4.7, so I think this is a
regressin in 4.8. I haven't had the opportunity to test with non-staging, hence
I'm filing this bug under staging.
