$DESKTOP on 98

markus · 27th January 2004, 20:56

on Windows 98 SE, during the installation, it seems as if $DESKTOP is defined as "C:\WINDOWS\All Users\Desktop\", but during the uninstall, it seems as if $DESKTOP is defined as "C:\WINDOWS\Desktop\".

Can someone confirm/deny this?

what is really strange is that both of these locations are valid locations to place items that should appear on the desktop for all users.

please note that i am using "nsis20rc2.exe"

thanks,

You probably forgot to use SetShellVarContext all in the uninstall section too. The uninstaller doesn't remember what you've set using SetShellVarContext in the installer.

Kichik,

Even I have noticed this issue.
On win98, irrespective of the shellvarcontext, $DESKTOP always points to C:\Windows\Desktop.

I experimented by putting the following code in the uninstaller.

SetShellVarContext current
MessageBox MB_OK $DESKTOP
SetShellVarContext all
MessageBox MB_OK $DESKTOP

And in both the cases it gave me "C:\Windows\Desktop" on win98 se. It works on all other OS.

Is this a bug in NSIS 2.0( version I am using )

This is probably Win98 bug, because
SHGetSpecialFolderPath(NULL, b, CSIDL_COMMON_DESKTOPDIRECTORY, false);
returns NOERROR, but buffer remains empty. For CSIDL_DESKTOPDIRECTORY this works correct. As a result
... NSIS\Source\build.cpp(451): m_ShellConstants.add("DESKTOP",CSIDL_DESKTOPDIRECTORY, CSIDL_COMMON_DESKTOPDIRECTORY);
based on the SHGetSpecialFolderLocation (?) not finds this folder. But folder is correctly defined in Registry ("HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\explorer\Shell Folders" "Common Desktop"). Now it is possible to use registry value in installation script (while NSIS sources are not patched).

maybe SHGetSpecialFolderPath needs Win98 SE

I tested on Win98 SE (had not older version

), and placed shortcuts both to "all" and "current" folders, this worked - shortcuts appeared on the Desktop. IMHO folders mapping to Desktop works fine, problem in the system call.

It is some kind of a weird initialization problem. See this bug report for more information and a temporary solution.
