SethOutPath removes ':'
Hey.

I use this code to get a path to the programData folder:

   Push $1
   System::Call 'shell32::SHGetSpecialFolderPath(i $HWNDPARENT, t .r1, i ${CSIDL_COMMONAPPDATA}, i0)i.r0' 
   StrCpy $g_strSettingsDir " $1\${PRODUCT_PUBLISHER}\${MUI_STARTMENUPAGE_DEFAULTFOLDER} ${PRODUCT_VERSION}\${PRODUCT_NAME}"
   MessageBox MB_ICONEXCLAMATION|MB_OK $g_strSettingsDir
   Pop $1

When i print g_strSettingsDir in a dialog i get the correct path.
But when I use it with SetOutPath the ':' is removed from the path.

The dialog:
http://oi51.tinypic.com/2mwhs8g.jpg
And when I run the installer:
http://i56.tinypic.com/x0z72s.png

As you can see, the ':' is gone and the program won't install correctly

Any ideas of why this happens?

Edit: Topic should be SetOutPath...

StrCpy $g_strSettingsDir " $1\..." you have a leading space, that is probably the problem.

Any why system plugin?

Just use SetShellVarContext all + $APPDATA

Next time you use message box, remember to use messagebox mb_ok "|$var|" or something like that

Thanks you!

Now it works! But why would that space remove ':'?

I don't remember the specifics on how NSIS validates a path, but I know what a valid win32 path looks like:

c:\foo = full path to foo
:\foo = foo at root of current drive
c:foo = foo in current directory on drive c

foo:bar = alternative data stream named bar on filesystem object foo in current drive/directory

...so : as a drive separator can only appear as the 1st or 2nd character
