Problem with registerExtension.nsh

Hi,

I have small problem with registerExtension.nsh
http://nsis.sourceforge.net/File_Association

I use:
${registerExtension} "$INSTDIR\installer.exe" ".mcr" "MCR File"
${unregisterExtension} ".mcr" "MCR File"

it gives me this error when compiling:

Section: "Uninstall"
!insertmacro: unregisterExtension
Push: .mcr
Push expects 1 parameters, got 2.
Usage: Push string
Error in macro unregisterExtension on macroline 2
Error in script "E:\Installer.nsi" on line 250 -- aborting creation process

It has a problem with quoting spaces, among other things. It also corrupts some variables. That script needs some work.

I've fixed your specific problem in the Wiki. Try it now.

Appreciate your help.

I have now this exception:
!insertmacro: unregisterExtension
Push: .mcr
Push: MCR File
Call must be used with function names starting with "un." in the uninstall section.
Usage: Call function_name | [:label_name]
Error in macro unregisterExtension on macroline 3
Error in script "E:\Installer.nsi" on line 280 -- aborting creation process


I tried calling:
${unregisterExtension} ".mcr" "MCR File"

from "Uninstall" section and un.onInit function.

Did I missed anything?

Thanks again

Another problem with the script. It defines unregsiterExtension as an installer function instead of an uninstaller function.

I've fixed that now as well. Try again.

Thanks it works fine now.

I just have small comment. It seems that reboot is required to refresh the icon of the file. I couldn't find a way to rebuild IconCache.db directly.

In Windows XP

- Go to C:\Documents and Settings\{username}\Local Settings\Application Data
- Delete IconCache.db
- Reboot

In Windows 9x

- Goto c:\windows
- Delete ShellIconCache
- Reboot.

RefreshShellIcons should do the trick.

Thanks for the help. It works.

I have another question. Is there a way to let clicking multiple files (at once) goes as parameters to one EXE instance instead of passing each file to one instance of the EXE file i.e.

program.exe <File1 Path>
program.exe <File2 Path>
program.exe <File3 Path>

And I need it to be:

program.exe <File1 Path> <File2 Path> <File3 Path>

Thanks

That requires a shell extension.
