wine users - May 2010 - Metatrader Installation error

I am experiencing a problem with the installation of Metatrader4.

The problem is that at the end of the installation I receive an error message:
'Error changing registry data'. The system then proceeds to carry out a
roll back routine.

I have previously managed to complete this on a Sony Laptop running Ubuntu 9.10
(Karmic) with Wine 1.1.42. Wine has since been updated to 1.1.43 and Metatrader
still works, having been previously installed.

However, I have since tried on another PC system with the same software releases
with the error result above (initially Wine 1.1.42, then 1.1.43). I have also
installed Ubuntu 10.4 (Lucid) on this PC and have the same result. The PC is
running the 64 bit version of Ubuntu, so in case this might be the problem, I
have also tried the 32 bit version (albeit installed as a Virtual Machine). In
both cases, the MFC42.DLL file was present and I have run (installed) both
'winetricks' and 'corefonts' in both environments.

Interestingly, when I first tried the installation on this system, I believe it
actually installed but then failed to run, with an error regarding MFC42.DLL
being missing. I can't remember what I did, but when I then tried to
re-install it, I then received the registry update error message, and have done
ever since with 9.10 and 10.4 (64 bit) and 10.4 (32 bit) via VM.

On the Sony system, where I have it installed successfully, I did install
'winedoors' but then un-installed this. I don't know whether
something was 'left behind' that enabled the installation to complete.

I would be grateful if anyone has any ideas on what might be causing this, or
what I can try.

However, I reiterate that I do have MFC42.DLL present. So unless there are
different versions of this, then the lack of this library is not the problem.

Thanks, in anticipation.

	Try the following:

unset WINEPREFIX
mv ~/.wine{,.old}
wineboot
winetricks vcrun6
wine start /unix /path/to/metatrader4/setup.exe

	If it still doesn't work please tell me.

	Thank you for using Wine.

OK.

Firstly, WINEPREFIX was not set in the environment, which may or may not be a
different problem.

Moved and recreated the .wine directory as suggested. (Some
'interesting' CLI syntax there. I'll have to go through that and try
and understand it :?).

This solution worked, although it would lose any other app or 'C-Drive'
info that was already present. Therefore, other than the fact that the
recreating of the .wine directory ensures a clean start, the significant element
would appear to be 'winetricks vcrun6'. So, I then used this command in
the other installation I have, without first recreating the .wine directory.

This also worked, so would appear to be the 'real' solution.
