Archive: Signing uninstaller.

Signing uninstaller.
I tried this piece of code but it keeps giving me errors:

!system: returned 0
!system: "C:\DOCUME~1\Yoshi\LOCALS~1\Temp\Setup.exe"
'C:\DOCUME~1\Yoshi\LOCALS~1\Temp\Setup.exe' is not recognized as an internal or external command,
operable program or batch file.
!system: returned 1, aborting
Error in script "C:\Documents and Settings\Yoshi\My Documents\NSIS\Visual Report Writer Developer Deployement Setup\VRWDER v0.4\signtest.nsi" on line 17 -- aborting creation process

Line 17:
!system "$%TEMP%\ Setup.exe" = 2

Wrong path? There is a space there...

Removed the space but I am not understanding this at all..
