All prerequisites failed, and later failed to change PATH variable when installing 11gR2

OS: Windows 7 x64.

Had issue when all the prerequisites check always fail while installing Oracle database. You can ignore that yes, but later when installer tries to write PATH variable - it just hangs for indefinite time, no errors no nothing.

There are quite a few posts around the Internet about this problem, but none of the recommendations actually helped:

1) Server service up and running, c: drive mounts just fine.

2) obviously, running installation from admin user with admin rights (in fact i can't see how you can do otherwise if UAC automatically demands elevation for setup.exe/oui.exe)

A usual bunch of error codes i received:

PRVF-7531: Physical memory check cannot be performed on node ... ensure access...PRVF-7536 : Architecture check cannot be performed on nodeetc. etc.

In my case the problem as it seems was non-ANSI symbols in user profile path. From installer log:

INFO: Verification Result for Node:BOBSWARNING: Result values are not available for this verification taskINFO: Error Message:PRVF-4001 : Check: Space available on "C:\Users\3C5C~1\AppData\Local\Temp"INFO: Cause: Could not determine mount point for location specified.

Although other checks did not have any complains about user profile path, but when i ran installation from a clean user profile, named "user", all the checks passed with no warnings and installation succeded afterwards.

Incidentally, it appears like most messages about this error are coming from people from not English-speaking countries, which kinda makes sense then.

So the prerequisite checks you ignored are what?

First i ignored all of them, because they all failed for no reason.

Running under user with a profile without non-ANSI characters I didn't ignore any, they all passed.

It seems that prerequisite check do not actually fail in this case, installer simply can't start them or connect them or get their output because of the DOS-like path (C:\Users\3C5C~1).
