问题
I am getting an odd return code from msiexec when installing an MSI. Namely, -2147021886. I THINK I remember reading somewhere that this is some sort of format or encoding issue, but I can't find the reference. I also found a microsoft page that talks about PS2.o having issues with negative return codes, but this is happening in PS5.0.

"The Magic Number Database": I recently discovered magnumdb.com (cleared virustotal 30-9-2018) in a tweet from Remko Weijnen.
"The Magic Number Database"is apparently maintained by Simon Mourier.Looking up your error code: https://www.magnumdb.com/search?q=-2147021886
1 ERROR_SUCCESS_REBOOT_REQUIRED Int32 -2147021886 %ProgramFiles(x86)%\Windows Kits\10\Include\10.0.17134.0\shared\winerror.h(11960,0)
Other Approaches: Including a couple of other options for similar situations.
Visual Studio (2017): Menu choice:
Tools => Error Lookup. This Visual Studio tool (errlook.exe) can be found in the"Tools" folderof your Visual Studio installation. N.B! Localized messages! (internationalized).cmd.exe: Via the command line, the
net commandcan normally be used to look up error codes:net helpmsg errorcode. See blog link below for limitations.certutil.exe: Try it via cmd.exe:
certutil.exe /error errorcode. Not sure if this is available in a clean install, but with Visual Studio it should be already available. Appears very good! Localized messages.Err.exe: An old tool from the Exchange team. Dated now. See blog link below - in the comments. Needs download. English messages, non-localized.
And in C++ the FormatMessage call. And just mentioning the winerror.h and ntstatus.h files. Retrieving the Last-Error Code. And a Powershell blog.
calc.exe: And obviously use the new Windows 10 calc.exe in "Programmer Mode" to convert between hex / dec and all kinds of other tasks:
