some special folders don't always work in Windows 9x

Script file for test

After some playing around with the script you've attached,
I've found that the reason $DESKTOP shows the right value
for the installer but not for the uninstaller is that you
have a CreateShortcut line in your installer. I will keep
trying to figure out what's really behind this, but for now,
you can add a CreateShortcut line to the uninstaller before
using shell constants such as $DESKTOP.

Thanks for your hint. I tried it and it works fine.

Will this bug be fixed in a later version?

Assuming I can find some way to work around this odd Windows
behavior, it will be fixed.

How exactly should the workaround look like?

If I add in the uninstaller section the following (as I
understood your hint):

CreateShortCut "c:\windows\Desktop\test.lnk"
"$INSTDIR\test.exe" "" "$INSTDIR\test.exe"
Delete "c:\windows\Desktop\test.lnk"

the Uninstaller well creates the link in case it did not
exist yet, but it does not remove it, altough I didn't use
any Shell variable.

Using NSIS 2.05 and Win98

Hello Jochen,

the workaround for a link on the desktop should look like this:

Section "Uninstall"

SetShellVarContext all
Delete "$DESKTOP\test.lnk"

CreateShortCut "$DESKTOP\test.lnk" "$INSTDIR\test.exe"
Delete "$DESKTOP\test.lnk"

SetShellVarContext current
Delete "$DESKTOP\test.lnk"

SectionEnd

Hey TDMFraggle,

thank you for the quick answer!

Unfortunately your hint does not work entirely:

I placed your code before all other uninstall-orders in my
"Uninstall"-Section.
And really, it removes test.lnk on my Win98 Desktop, but
creates a new one at the same time, wich is not deleted.
I assigned a different icon to that shortcut created in the
uninstaller-section, to make this effect visible, otherwise
it seems that test.lnk remains just untouched.

Do I need to post the whole Installer-File?

Put this above your code instead:

CreateShortcut $TEMP\temp.lnk $TEMP
Delete $TEMP\temp.lnk

No success :-( Icons still exist ...

here my complete Uninstaller-Code:

Section "Uninstall"

CreateShortCut "$TEMP\temp.lnk" "$TEMP"
Delete "$TEMP\temp.lnk"
Delete "$DESKTOP\Start Fernwartung.lnk"
Delete "$DESKTOP\Stop Fernwartung.lnk"
RMDir /r "$INSTDIR"
RMDir /r "$SMPROGRAMS\IT-Vogl"
DeleteRegKey HKLM
"Software\Microsoft\Windows\CurrentVersion\Uninstall\${PRODUCT_NAME}"

SectionEnd

(the reg-part in one line of course)

You still need SetShellVarContext all. Add it back and it
should work.

Unfortunately it didn't. I placed it on top and in another
try between the Uninstaller-Code I submitted before you posting

- witout any success.

Try replacing $TEMP with $DESKTOP. Maybe not all
CreateShortcut commands make it work. If you still can't get
it to work, try creating a thread in the forum with a link
to this ticket. You'll probably get faster responses.

Finally fixed this using a call to SHGetFileInfo which does
the same trick as CreateShortcut. Please confirm using
tonight's nightly build:

http://nsis.sf.net/nightly/nsis.zip

It should be updated in around 3 to 4 hours.

The source diff will be available at the following address
at around the same time:

I'm closing this for now because version 2.11, along with
this fix, will be released tomorrow. Please do let me know,
if there are still problems with this.
