Inno and Vista

[Darkbob]

So I've got an application with a few MDB's.

The majority of my customers use XP (for now) so I put my data in a folder under the application's EXE's like this:

MyApp\app.exe
MyApp\Data\Data.mdb

To avoid security problems under Vista I'd like to put the MDB's in the right place. I'm told that's in the Public folder but I'm not overly clear on that point.

Any tips on using Inno so it works with both XP and Vista?

Thanks!

In order to keep it segragrated from other apps too.


Try seeing is Inno supports environment variables (I never used Inno):
%ALLUSERPROFILE%

Should be the "C:\Users\Public" in Vista

"C:\Documents and Settings" in XP.

Yes, Inno Does support environmental variables...

From Inno Setup Help Documentation:


{%NAME|DefaultValue}

Embeds the value of an environment variable.

NAME specifies the name of the environment variable to use.
DefaultValue determines the string to embed if the specified variable does not exist on the user's system.

If you wish to include a comma, vertical bar ("|"), or closing brace ("}") inside the constant, you must escape it via "%-encoding." Replace the character with a "%" character, followed by its two-digit hex code. A comma is "%2c", a vertical bar is "%7c", and a closing brace is "%7d". If you want to include an actual "%" character, use "%25".

NAME and DefaultValue may include constants. Note that you do not need to escape the closing brace of a constant as described above; that is only necessary when the closing brace is used elsewhere.

Examples:

{%COMSPEC}
{%PROMPT|$P$G}

I will just be using the above in XP and Vista

That path is not valid for XP unless you create it but then your XP limited users may not be able to execute or modify files in it.

Also, you really should place code or a check of some kind in case they try to install on 2000 or 98 or ME etc. Users will be users.

Thanks for all the info.

I'm not much of an Inno expert but seems to me there should be some kind of conditional logic available to help you with a Vista vs XP install.

There's the environment variable: %ALLUSERSPROFILE%

So if you could do something like this:

If %ALLUSERSPROFILE% = C:\Documents and Settings then
... Install wherever I like
else
... Install into the C:\Users\Public\MyApp folder
end if

But I can't figure it out... so does Inno have anything like this?

I have just asked the same question in another thread. So, can Inno detect Vista and consequently change the installation folder?

[randem]

Yes, I answered that question...

Use MinVersion and OnlyBelowVersion to detect OS's for conditional installation of files.

[Darkbob]

You can decide whether or not to install files based on the OS revision but I haven't found a way to do branching or conditional logic other than that. For example I haven't found a way to install to one folder if it's XP and a different folder if it's Vista.

I suppose you could just write your entire install twice and put conditions on every single line. One install for Vista and one for XP. But that's kinda kludgy.

[randem]

I image you can write code to change the DefaultDir parameter depending on the OS version.

[Darkbob]

Yes, that would be cool and exactly what I was asking about. But I can't see any way to do it. Any Inno experts out there have any ideas? Or is there another installer I should be looking at?

Ask Klienma, he hangs out in the .NET forum. He does Inno Setup code.
