How to create a destname which includes date and time at installation in Inno Set-up

Question

I want to use the [Files] section to create a new file which has the format:

Program Name plus date plus time .fmpur

I'd be grateful for any ideas.

Answer 1

For instance the following way. How to modify a date time pattern, see the GetDateTimeString page:

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program

#define FileNamePattern SetupSetting("AppName") + " " + GetDateTimeString('dd-mm-yyyy hh-nn-ss', '-', ':') + ".fmpur";

[Files]
Source: "MyProg.exe"; DestDir: "{app}"; DestName: "{#FileNamePattern}"
