Problems calling 64 bits Dll

[jmaravilla]

Hello

I'm trying to call 64 bis DLL, but when i call the DLL i get this message "EXTERNALEXCPETION" i'm using the Installware Studio Admin 18, my application is in 64 bit installation mode on 64 bit windows. I searched in others posts and found this post viewtopic.php?f=2&t=5822, is the installaware 18 compatible with calling 64 bits dll? or How can i call a 64 bits dll ??


Thank you

Dear User,

unfortunately, you can't.

The Windows Installer process, it is Always a native 32 process and consequently, you can't execute a 64 bit dll from it.

This is not an InstallAware limitation.

The only possible alternative it is to create a 64 bit Exe that calls that dll and then to execute the Exe from your script.

Hope this helps you.

Regards
