vs_communitycore.msi can't be executed - error code 1619

I'm having problems with my old VS 2015 installation on Windows 7, I cannot repair/uninstall it, It seems the packages were corrupted after I migrated my operating system.

I have manually uninstalled all msi files reported on error logs and could perform a new install from a ISO file. But after install I still can't open Visual Studio, repairing or uninstalling fails because some component could not be loaded.

I tracked down the problem to the vs_communitycore.msi located at C:\ProgramData\Package Cache{DE064F60-6522-3310-9665-B5E3E78B3638}v14.0.23107\packages\communitycore\Setup\ This package is also contained in the ISO file, it gives the same error message and I have already checked the ISO integrity with fciv.exe.

If I try to open the vs_communitycore.msi file it gives me an error: "This patch package could no be opened. Verify that the patch package exists and that you can access it, ..."

This seems to be the same error reported on the vs setup log (aka error code 1619):

[1208:0CA0][2018-07-26T01:45:03]i000: MUX: Set Result: Return Code=-2147023277 (0x80070653), Error Message=, Result Detail=, Vital=True, Package Action=Uninstall, Package Id=vs_communitycore

I don't think the problem is installation corruption. It looks like it because when I try to open some MSI files the execution fails with error 1619, like the MSIs were not valid ones; but I have downloaded them many times and checked the ISO integrity as well. The error appears if I try to open the same file directly from the ISO too.

It is weird, why would a freshly downloaded MSI fail with 1619 ?

I ran the visualstudiouninstaller tool, the first time it removed a bunch of stuff. But it looks like some MSIs fail to uninstall and now every time I run it gives me the same output (see below).
