Hi, looks like the "An installation support file could not be installed"-bug was
fixed in wine-0.9.21 but reintroduced in wine-0.9.27. Tests were done using
Heroes of Might and Magic V and the 1.01 patch. The commits that caused the
changes are:

ole32: Remove some assertions in the stuctured storage code by returning error
codes to the caller and by handling the error condition.

Before this commit I recieved the "An installation support file could not be
installed" error box when trying to install the patch while Heroes V is
installed. (Oddly enough I don't get this error if I run the patch installer
without having the game installed.)

After this commit this bug seemed to be fixed: I can run the patch installer
without getting the "An installation support file could not be installed" error
box. (But the patch won't install due to bug 6364).

ole32: Fix logic in Storage32Impl_SmallBlocksToBigBlocks function.

After this commit however, the patch gave the "An installation support file
could not be installed" again. Seems like a regression.
