Since the amount was marginal from the requirment I decided to allow this. But of course you can't check this in installaware. My solution was to use the windows api to get the information. Another problem was that installaware couldn't handle the structures needed.
To solve this I wrote a dll in powerbasic that is interfaced in the installer.
I have attached the source code and the compiled dll file. To use the dll you must add it into support files in the installaware ide
Code: Select all
TYPE MEMORYSTATUSEX
dwLength AS DWORD
dwMemoryLoad AS DWORD
ullTotalPhys AS QUAD
ullAvailPhys AS QUAD
ullTotalPageFile AS QUAD
ullAvailPageFile AS QUAD
ullTotalVirtual AS QUAD
ullAvailVirtual AS QUAD
ullAvailExtendedVirtual AS QUAD
END TYPE
DECLARE FUNCTION GlobalMemoryStatusEx LIB "KERNEL32.DLL" ALIAS "GlobalMemoryStatusEx" (lpBuffer AS MEMORYSTATUSEX) AS LONG
FUNCTION TotalSystemRam ALIAS "TotalSystemRam" () EXPORT AS LONG
DIM objMemoryStatus AS MEMORYSTATUSEX
DIM lngResult AS LONG
objMemoryStatus.dwLength = LEN(objMemoryStatus)
lngResult = GlobalMemoryStatusEx(objMemoryStatus)
TotalSystemRam = CLNG((objMemoryStatus.ullTotalPhys \\ 1024)\\1024)
END FUNCTION
To use the dll in your script all you need is to cut and past the code below into your MSI Code where you normal check your memory requirment. I have attached the comparison code as well but you will need to tweak the message and amount of ram to your requirment
Code: Select all
