Hello Nikolay,

Maybe I missed something, but how does a private heap help with a corruption?
It could be less destructive but if it's not where a real problem is why do we
need this workaround?

yes, it doesn't really fix it - until the real cause is found.
It reduces the probability of encountering a crash during install time
considerably.
There is already a high congestion in the heap for small blocks during run of
installer, increasing the likelihood of 'collateral damage' by any win32
component.

It's not uncommon for MS installers to rely/make use of undocumented (internal)
data structures, in this case setupapi.

Having a separate heap/wrappers might ease the task of isolating the actual set
of API which causes the corruption.

Regards
