Hi,
We have been developing apps for use under Windows since the Windows 3.1
days. Microsoft published some application design "rules" (esp where
executables and data should be stored) way back then but didn't really
enforce them. However, they did say that they would enforce at some future
date ! Many developers (including us) thought they new better and
implemented their own standards. Starting with MS-Vista and definitely in
Windows-7 & Windows 2008 Server, Microsoft are now actively enforcing those
rules.
As a result of the "enforcement" by Microsoft, we had to change our
application (especially the folders & data structures) to match the "new"
rules. The changes didn't really affect the operation of our apps - we just
had to "follow the rules"
PS When you look at the "rules" set out by Microsoft, you realise that
they do make sense and to change your app is usually not that onerous.
These are a very brief summary of the more pertinent items - check MSDN for
more details ...
--> Folder usage
Microsoft want all applications to install their executables under
{ProgramFiles} C:\Program Files\Company\....
and all application data under one of two folder structures
{CommonAppData} C:\ProgramData\Company\...
or
{UserAppData} C:\Users\Owner\AppData\Local\Company\...
As the local NetAdmin can change the location of these via Group Policies,
it is better to retrieve the path to these folders using WinAPI calls as
your app initiates.
--> Shared Memory
This was being used by many "nasties" (virus/worm/etc) and is now generally
blocked (it can still be used but you need to check MSDN)
--> Installers & Admin Accounts
It is better to 'require' the installation to occur under a local admin
account and for the installer to perform the necessary steps
- create 'base' application folder structures
- establish appropriate security on these folder structures
- create User/Password for any service account to be used
- assign User Rights as required
- install any services (incl. Nexus Engine)
This is relatively easy to do using INNO setup - we assume it also can be
done using other installers.
We found that a few simple changes removed almost all of the installation
and operational issues we had without the need to require users be setup as
Administrators.
Regards,
Brian

Subject: Re: NexusDB - Windows 7
Hi Andre,
Yes, thanks for that, I 'think' I have managed to set the user as the
Administrator, but as I am not fully up to speed with Win 7 yet, there is
some uncertainty - it is quite confusing in the way I seem to be doing
it - more than one way in, and some of the settings don't make sense
(typical M$ stuff).
I think the main thing I am really after, how does one set up the
different apps, NexusDB server, turn it on, and install the Delphi App
automatically (or remotely), say using Inno (preferred) or InstallAware
installers?
I may be dumb (don't answer that!!!!!), but some of my clients leave me
for dead ......... (how they even use that roll of paper, I don't
know....)
Cheers,
Frank
Hi Frank
I'm not sure if this is appropriate but some apps I've written in Delphi
need to be run as Administrator under Windows 7 otherwise there are all
sorts of problems with creating folders etc...

Hi All,
I have several projects that use NexusDB (and go very well) (still
running
on XP).
I need to put one of them onto a Windows-7 laptop, the NexusDB Server,
the
program, and the NexusDB Enterprise Manager.
I've done this once before, onto another Win-7 laptop, and it worked
then,
but I can't remember what I did.
When I try it now, I just keep getting messages that the NexusDB is
locked,
or that a file is locked.
Any ideas?
Maybe I need to install it using Inno, but what settings do I use then?
