Hi all
It is my first ever post here but hopefully this will go a long way to
solve a lot of heartaches and unnecessary clean installs.
I did a bit of research on the net... some articles giving some hints
that 0xc0190036 is caused by the target file to be patched during SP1
installation being CORRUPTED. The file with error 0xc0190036 being
reported during SP1 installation, in my case, was Firewall.cpl (it can
be ANY file targeted for patch by SP1). I booted from a WinPE CD and
ran a chkdsk /f on my C: drive... and sure enough, Firewall.cpl was
found to be corrupted.
Chkdsk went ahead to try to fix the corrupted file. After that I
rebooted the system and let the HDD boot partition run. No luck, the
SP1 installation still hang at overwriting Firewall.cpl. So out of
frustration, I booted back into the WinPE CD.. this time I simply
deleted the corrupt Firewall.cpl away. I proceeded to reboot the
system back into the C: boot partition. This time it worked like a
charm - the SP1 installation simply put a new copy of the deleted
corrupted file into the HDD, and went on to complete the SP1
installation. The desktop showed up pretty shortly thereafter - SP1
update complete!
Search 0xc0190036 on the net and you will find that quite a few people
hit it during SP1 install - but M$ simply provided no explanation on
it. Now you have it here - hopefully this is the first complete
definition and resolution of the 0xc0190036 error that has ever been
posted on the net.
P.S. if you hit the same problem but have no WinPE CD, fret not - the
original Vista installation DVD has a command prompt repair function
and it will let u run chkdsk and to delete files equally well as the
WinPE command prompt.
Possible causes and mitigation factors to prevent file corruption just
prior to SP1 install (and hence prevent the dreaded 0xc0190036 error):
- HDD was already somehow corrupted beforehand. Resolution/prevention:
run a chkdsk /f on your boot partition BEFORE you attempt to download/
install SP1!
- Automatic defragmentation somehow causes some files to be corrupted
the moment SP1 installation reboots your system. Resolution - disable
any and all background HDD defragmentation programs before attempting
SP1 install!
