EndInstall() Call Returns Zero But SAP Still Times Out?

Question

Hi,
I have an add on installer where the setup.exe file was created and compiled using InnoSetup. Since switching from 32 bit to 64 bit it has been a struggle since there is so little documented by SAP on this. I finally found out that we cannot call the EndInstall and EndUninstall functions directly in AddOnInstallAPI_x64.dll like we could in AddOnInstallAPI.dll for 32 bit add ons. I created a Visual Studio wrapper project that contains the calls to EndInstall and EndUninstall and I launch that compiled executable at the end of my setup.exe installation procedure. I have logging inside the wrapper which gives me the result of the EndInstall call and it is returning a 0 which means it was successful. Even still, SAP still sits until it times out and tells me the add on registration failed and it needs to be corrected. Oddly enough, if I run my wrapper executable manually right at the end of my installer, SAP does get the signal and says the add on was installed successfully.
I need to get this resolved so I can do a required add on upgrade. Has anyone else experienced this?  Is there any way yet that we can call the 64-bit functions directly from the DLL file yet?  Why has SAP not addressed this yet?
Thanks,
David

Hi Pedro,
I've tried both EndInstall and EndInstallEx directly from the 64 bit DLL but neither worked. Here was my code in InnoSetup to call EndInstallEx.
function SetAddOnFolder(Path: String): Integer;
external 'SetAddOnFolder@{code:TargetDir}\extern\AddOnInstallAPI_x64.dll';
function RestartNeeded(): Integer;
external 'RestartNeeded@{code:TargetDir}\extern\AddOnInstallAPI_x64.dll';
function EndInstallEx(Info: String; InstallSucess: Boolean): Integer;
external 'EndInstallEx@AddOnInstallAPI_x64.dll';
function GetCustomSetupExitCode: Integer;
var
  nResult: Integer;
begin
nResult := EndInstallEx('', true);
end;
You think this should actually work?
Thanks,
David
