DefaultDirName IN inno

Hi,

I want the following: at first installation my Inno-setup has to tell 
the customer an installtion directory I write into the property 
DefaultDirName. At second installation on same PC (update) it should use 
a value from registry, which tells Inno, where the software is allready 
installed.

I have no idea, how to do that. Any suggestions?

Kind Regards

Jan,

If you check the on-line help of Inno Setup, what you want is the 
default behaviour:

DefaultDirName

Description:
The value of this required directive is used for the default directory 
name, which is used in the Select Destination Location page of the 
wizard. Normally it is prefixed by a directory constant.

If UsePreviousAppDir is yes (the default) and Setup finds a previous 
version of the same application is already installed, it will substitute 
the default directory name with the directory selected previously.

Hi Geoff,

I'll check that. The problem I have: because of some Vista-Problems I 
changed the DefaultDirName from c:\programme\apas\fsm to c:\fsm. Since 
that my customers everytime, when they install an update, receive c:\fsm 
  . Since not any customer reads, what he does, my updates fire into 
wrong direction...

Kind Regards

Jan,

New Windows security wants you to install in "c:\Program Files" or the

equivalent in your language version of Windows. Inno Setup has the 
Directory Constant  which you can use and it will install correctly 
in an language version of Windows.

Inno already know where your software is installed by user first tim at 
updates .. ???

Only if you change the SETUP->AppID (AppName as DEFAULT) entry than it is a 
new app for Inno and than give problem so Inno dont know the first entries 
make by user....
