[issue34565] Launcher does not validate major versions

[issue23855] Missing Sanity Check for malloc() in PC/_msi.c

Zackery Spytz added the comment: The suggested patch is not acceptable: MemoryError should be raised in the unlikely event of a malloc() failure, there's a missing call to MsiCloseHandle(), the use of tabs violates PEP 7, and there's a blatant syntax error. -- nosy: +ZackerySpytz
