Custom InstallDir from Registry+subfolders
Hi. I am a newbie at programming, so I have difficulties in doing this: I'm trying to build an installer that gets a path for the INSTDIR from the registry and then concatenates that with something else. For example, I have a string value in the registry that is : "C:\Myprogram\". I want to add to that path (without changing the registry) a subfolder, like "C:\MyProgram\Install Here". How do I do that ? :cry:

I also have a question about RegDLL. I get an error message that says "unable to load DLL". If I use RegSvr32, it works OK.

Thanks.:winamp:

In .onInit, change $INSTDIR with StrCpy. For example:

Function .onInit
StrCpy $INSTDIR "$INSTDIR\Install here"
FunctionEnd

Thank you kichik. I'm trying to use InstallDirRegKey to get the path from the registry. Lets say its "C:\MyProgram\". How do I tell the installer to copy sme files to "C:\MyProgram\Folder_1" and then to copy something else to "C:\MyProgram\Folder_2", using the path from the registry ?

Read some examples into NSIS folder.
For example you can use:
InstallDir "$PROGRAMFILES\MyProgram" #default value
InstallDirRegKey HKLM "somepath" "somekey" #previous path (will override default value)
Section "Section_Name" SEC01
SetOutPath "$INSTDIR\Folder_1"
File "file1.exe"
File "file2.exe"
SetOutPath "$INSTDIR\Folder_2"
File "file3.exe"
<other commands>
SectionEnd
Section -Post #to remember new Path, if you will change it with Browse button
WriteRegStr HKLM "somepath" "somekey" "$INSTDIR\filename.exe" #filename.exe - file from your program
<other commands>
SectionEnd
