Consider the following:
I have two files, for example XXX.txt and YYY.txt
I want to install them to a folder (let's say files), in which there are already XXX.txt and YYY.txt files
I want to "back up" the two original files, renaming them to XXX.txt.backup and YYY.txt.backup
On uninstall I want to restore the two files to their original state
How can I achieve this with Inno Setup?
Add
[Files]
; Backup Function_Template
Source: "{app}\XXX.txt"; DestDir: "{app}"; DestName: "XXX.txt.bkup"; Flags: external skipifsourcedoesntexist uninsneveruninstall
That would move the existing file, and the flags will prevent from uninstalling it. Now in the code you can put
[Code]
procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep);
var
OldFile: string;
begin
case CurUninstallStep of
usPostUninstall:
begin
OldFile := ExpandConstant('{app}\XXX.txt.bkup');
if FileExists(OldFile) then
RenameFile(OldFile, ExpandConstant('{app}\XXX.txt'));
end;
end;
end;
Source: "{app}\XXX.txt"; DestDir: "{app}"; DestName: "XXX.txt.bkup"; Flags: external skipifsourcedoesntexist uninsneveruninstall
Did not appear to work, since "The compiler will prepend the path of your installation's source directory if you do not specify a fully qualified pathname."
However, I just discovered this works fine! I had left off the "external" flag.
Well, maybe a popup saying "There is already an XXX.txt.backup. Do you really want to overwrite it?"

I have created files for a program I want to make as an update.
I would like it, before the installation, to check whether the program is also in the standard directory, and if not the one itself the right directory can choose where the program is.
I have tried this:
[Files]
Source: "C:\Data"; DestDir: "{app}"; Flags: ignoreversion
[Code]
function NextButtonClick(PageId: Integer): Boolean;
begin
Result := True;
if (PageId = wpSelectDir) and not FileExists(ExpandConstant('C:\Program\Test\Test.exe')) then begin
MsgBox('YourApp does not seem to be installed in that folder. Please select the correct folder.', mbError, MB_OK);
Result := False;
exit;
end;
end;
But during the installation it does not check it.
Whether the program is available or not, it installs it anyway.
I hope someone can help me.
You have to use the {app} constant in the test to check the selected folder:
FileExists(ExpandConstant('{app}\Test.exe'))
I am using Inno Setup to build my installer and I have the C:\Users\Public folder hardcoded in my [Files] section to place some files (Inno Setup does not have a constant for this folder)
My goal is to have the install create a C:\Users\Public\MyApp folder with some files in it. However when I run the install, it is creating the folder here:
C:\Users\Public\Public Documents\MyApp
Is this a permissions issue where the installer doesn't have access to create a folder directly under C:\Users\Public?
[Files]
Source: "MyApp\db.mdf"; DestDir: "{drive:{src}}\Users\Public\MyApp"; Flags: ignoreversion;
I cannot reproduce your problem. For me your code works. I've tested it on Windows Vista, 7 and 10. It always installs to C:\Users\Public\MyApp.
Though I do not understand the {drive:{src}}. How does the drive of the Users folder relate to the drive of the installer? You should use the {sd} constant:
[Files]
Source: "MyApp\db.mdf"; DestDir: "{sd}\Users\Public\MyApp"; Flags: ignoreversion
But anyway, to resolve the path to the C:\Users\Public, you can use the PUBLIC environment variable:
[Files]
Source: "MyApp\db.mdf"; DestDir: "{%PUBLIC}\MyApp"; Flags: ignoreversion
It works since Windows Vista.
Alternatively, you can use SHGetKnownFolderPath with FOLDERID_Public. For an example code, see Constant for AppData\LocalLow?
If you need to support even Windows XP, where there is no C:\Users\Public folder or PUBLIC variable, you have to find out, what path your need to use there instead (probably C:\Documents and Settings\All Users), and implement a fallback using a scripted constant:
[Files]
Source: "MyProg.exe"; DestDir: "{code:GetPublicPath}\MyApp"; Flags: ignoreversion
[Code]
function GetPublicPath(Param: string): string;
begin
Result := GetEnv('PUBLIC');
if Result <> '' then
begin
Log(Format('PUBLIC is "%s"', [Result]));
end
else
begin
Result := GetEnv('ALLUSERSPROFILE');
Log(Format('PUBLIC is not set, ALLUSERSPROFILE is "%s"', [Result]));
end;
end;
And for others, it's worth noting that your need for resolve C:\Users\Public is very specific, related to this question: C++ app MDB in ProgramData copies to user's AppData folder when I dont want it to.
One usually does not want the C:\Users\Public, but C:\Users\Public\Documents (= {commondocs}) or C:\ProgramData aka C:\Users\All Users (= {commonappdata}).
Is there a way to dynamically fill the [Dirs] and [Files] sections of an Inno Setup script?
Here is what I am trying to do:
during the install process, the user will select foo (foo matches a repository to get from our SCM)
Setup will run a batch to checkout foo from our SCM
then the content of foo must be added to the [Dirs] and [Files] sections of the script
Everything works fine except for the last step. I searched around and couldn't find explanations on how to do this. I have the feeling that my script should embed all the repositories of our SCM to then be able to copy only the selected ones to the destination directory.
Thanks for your help!

See Inno Setup Prompt for external file location.
And add the recursesubdirs flag.
You may also need the createallsubdirs flag (assuming from your reference to the [Dirs] section).
[Files]
Source: "{code:GetScmPath}"; DestDir: "{app}"; \
Flags: external recursesubdirs createallsubdirs
[Code]
function GetScmPath(Param: string): string;
begin
Result := { make it return path to the checked out files }
end;
I have this line in .iss file:
Source: "..\Tcl\*"; DestDir: "{app}\Tcl"; Flags: ignoreversion
which packs folder Tcl. But it takes only files inside folder, but does not take subfolders inside Tcl. Is there a way to take entire folder Tcl with all subfolders and files? (without listing all that subfolders line by line).
Inno Setup 5.4.2.
Yes, there is. Simply include the recursesubdirs flag to your [Files] section entry. The help says about this flag the following:
Instructs the compiler or Setup to also search for the Source
filename/wildcard in subdirectories under the Source directory.
So, all you should do is modify your [Files] section entry this way:
[Files]
Source: "..\Tcl\*"; DestDir: "{app}\Tcl"; Flags: ignoreversion recursesubdirs
You can also use the Inno Wizard, but you'll need to correct the script afterwards if you would like those files to stay in the folder they're imported from, because the Wizard will put them in the app default folder.
The wizard wil generate:
[Files]
Source: "..\Tcl\*"; DestDir: "{app}; Flags: ignoreversion recursesubdirs
If you need to maintain the folder structure you'll need:
[Files]
Source: "..\Tcl\*"; DestDir: "{app}\Tcl"; Flags: ignoreversion recursesubdirs
Inno Wizard Update as of 5.6.1 (08/14/2018)
The Inno Setup Script Wizard now has the option to specify a subfolder. On the Application Files step of the wizard, use the Add Folder... button, then after you select the folder you would like to add, make sure it is selected in the list and then click Edit... and under the Destination Subfolder textbox, specify where you would like the previously selected folder contents to go.
I am trying to figure out how to rename a file in the file section while building the setup file.
I want to include a Local.config file but extract it as Local.config.tmp
I can't figure out why Inno Setup keeps creating folders instead of renaming files. So far I have this, but it keeps creating folders named Api\Local.config.tmp.
Any ideas?
[Files]
Source: "Api\Local.config"; DestDir: "{app}\Api\Local.config.tmp"; Flags: ignoreversion recursesubdirs
It's creating a folder as that's what you told it to do.
Try specifying a destination name:
[Files]
Source: "Api\Local.config"; DestDir: "{app}\Api\"; DestName: "Local.config.tmp"; Flags: ignoreversion recursesubdirs
