I'm lost, need to detect flash 6 or higher and install
I need to detect if Flash 6 or higher is on the system, and if not found install the flash player. Most important, I need to check if the flash player is installed for internet explorer. I don't care if its installed for any other browser, my application uses IE.
But... i'm completely lost (never worked with NSIS before). All examples I find only do a part of what I need, or don't work at all. Could someone please help me out on this one?

look in '$SYSDIR\MACROMED\FLASH' first if exists and if so, then compare version.

You can use this in VBScript:

checkForFlash6 = (IsObject(CreateObject("ShockwaveFlash.ShockwaveFlash.6")))

checkForFlash6 will be true or false.
Not sure how one would pass it from the VBScript to NSIS though.

On a side note, you could try searching your local registry for a registry entry that identifies which Flash version you have installed.

also in $SYSDIR is the easiest way:

!define FLASH 'flash.ocx'
!define CUR_VER '8.0'
outfile grabflash.exe
showinstdetails show

section

SearchPath '$0' '${FLASH}'
strcmp $0 '' _install
messagebox mb_ok 'Flash is here $0'
GetDllVersion '$0' '$R0' '$R1'
IntOp $R2 $R0 / 0x00010000
IntOp $R3 $R0 & 0x0000FFFF
IntOp $R4 $R1 / 0x00010000
IntOp $R5 $R1 & 0x0000FFFF
StrCpy $1 "$R2.$R3"
messagebox mb_ok 'computer version is $1'
intcmp '${CUR_VER}' '$1' +1 +1 _install
messagebox mb_ok 'current version ${CUR_VER} comp version $1 no install need'
goto +3
_install:
messagebox mb_ok 'current version ${CUR_VER} comp version $1 INSTALL need'

Is it safe to rely on particular file version? Maybe macromedia flash stores anything in registry?
