IF THEN ELSE... How with Wise for Win Installer

IF THEN ELSE... How with Wise for Win Installer

IF THEN ELSE... How with Wise for Win Installer

(OP)
Hi,
I must translate the following lines of a legacy setup into a msi package:

1) Search for a registry Key (ok, no problem)

CODE

Get Registry Key Software\.... Place in Variable APP_PATH
2) Conditional statement: a dll file must be installed in a specific folder:

CODE

IF APP_PATH Not Equal "" Then
   Install File %_Source_%\MyDLL.dll to %APP_PATH%\MyDLL.dll
ELSE
   Install File %_Source_%\MyDLL.dll to %MAINDIR%\MyDLL.dll
How can I translate this condition in WINDOWS Installer Editor (WISE PACKAGE STUDIO 5)?

Thanks

RE: IF THEN ELSE... How with Wise for Win Installer

I use Wise for Windows Installer 4.2.  I think you have two options:

Use 2 'If' statements in the Editor:

CODE

IF APP_PATH Not Equal "" Then
   Install File %_Source_%\MyDLL.dll to %APP_PATH%\MyDLL.dll
END

IF APP_PATH Equal "" Then
   Install File %_Source_%\MyDLL.dll to %MAINDIR%\MyDLL.dll
END

Or...

Create and run a wisescript at this point.  Wisescript is more robust and allows If, Then, Else, ElseIf statements.

Good luck,

Kate
