Question

while adding AccessControl NSIS fails with below error
Error: Can't change target architecture after data already got compressed or header already changed!
Error: Unable to set target charset (adequate stub not found?)
This is what i added in nsis, installed the plugin (pasted the dll in right folders), restarted the NSIS v3 app.

Answer 1

I can't tell what the exact problem is because you have not posted enough code but I can guess:
You are trying to target something you don't have the required stub files for, for example if your .nsi has Target amd64-unicode.
You are trying to change the target too late in your script. Unicode and/or Target should be as early as possible in your .nsi, before !includes and functions/sections.
Try this to make sure a simple script works:
!verbose 4
Unicode True
!echo "NSIS ${NSIS_VERSION} (${NSIS_PACKEDVERSION}, CS=${NSIS_CHAR_SIZE}, ${NSIS_CPU})"
!echo "Choosing zlib-x86-unicode (${NSISDIR})"
SetCompressor /Final zlib
!if /FileExists "${NSISDIR}\Stubs\zlib-x86-unicode"
!echo "Stub exists, everything should be OK"
!else
!warning "Stub not there? Reinstall NSIS?"
!endif
!ifdef NSIS_WIN32_MAKENSIS
!echo "Compiling on Windows"
!endif
!ifdef NSIS_UNICODE_MAKENSIS
!echo "Using Unicode compiler"
!endif

It should output something like this:
