Uninstall cant write to Var(s) or Read from Registry???

[vmsgman]

I found somewhere in the docs or forum that you should use the registry if you are creating the Uninstall file in a different directory than the Install Directory.

But the code below still does not seem to work. Any ideas?

Thx for you help! Greg


Section "Uninstall"

ReadRegStr $insDir HKLM "Software\Paxscan\Imaging Systems\Imagers\$serNum" "instdir" ; Install Directory
ReadRegStr $uniFil HKLM "Software\Paxscan\Imaging Systems\Imagers\$serNum" "unifile" ; Uninstall File

MessageBox MB_OK $insDir ; The message box shows nothing?

RMDir /r $insDir

DeleteRegKey HKLM "Software\Paxscan\Imaging Systems\Imagers\$serNum"
DeleteRegKey HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\$serNum"
; These seem to work fine !

Delete $uniFil ; Since $uniFil is "" this does not work

SectionEnd

Are your variables declared first?

code:


Var insDir

Var uniFil



Section "Uninstall"

    ...

SEctionEnd

[vmsgman]

Yes, they are declared first up before any sections. Like so ...
;-----------------------
;Variables

Var rcpExists
Var snPath
Var serNum
Var uniDir
Var uniFil
Var insDir

.... All the other stuff sections then Uninstall is the last section

Are you sure that registry key really contains what you're looking for? Did you write it in the installer? Is $serNum properly initialized? Where did you get $serNum from?

[vmsgman]

I guess that they are not properly initialized in the Uninstaller section. They were earlier in the script. I think I just thought of a workaround as the serial number is also available in the registry. Thanks for your prompt help.
