First of all: Thanks to all who contributed to this issue. There are
many helpful and interesting comments.
I am going to reply to Christian's first question: How did TEMP end up
with this value?
I have just scanned my installation protocol which says, that I made a
registry backup of the current user enviroment right after the basic
system installation. After that backup I restored the previously saved
Windows XP Pro x86 DE user environment. This step changed the TEMP
setting from its default value to "C:\Users\ADMINI~1\LOKALE~1\Temp"
(8.3 notation), which corresponds to
"C:\Users\Administrator\Lokale Einstellungen\Temp".
I unintentionally changed the TEMP variable from its default
setting. I should have checked whether the TEMP values has changed or
not - but I did not. Newertheless, I would not have expected any
problems from a changed TEMP setting even if it contains links.
From my backup of the original user environment
[HKEY_CURRENT_USER\Environment] I can reconstruct the default value of
TEMP:
TEMP=%USERPROFILE%\AppData\Local\Temp
which resolves to
TEMP=C:\Users\Administrator\AppData\Local\Temp
The default TEMP setting does not contain any links. As a link is
obviously causing the installer to fail, it will probably finish
without problems when using either the default TEMP setting or any
non-default setting that does not contain any links.
Before I am going to install with the default TEMP setting I am doing
the desired tests for the BitRock Support and wait for the answer.
I will keep the list informed about any new results.
