iawin32.dll and iawin64_x64.dll


Googling around, I can see it's a recurring issue for a long time, but mb somebody bumped into a feasible solution?

As I can see, when launched on Win64, IA unpacks iawin32.dll or iawin64_x64.dll into installation directory, depending on which kind of JVM (32- or 64-bit) was used to do the installation.
Thus, if for some reasons uninstaller attempts to use another kind of JVM (i.e., 32-bit for install, 64-bit for uninstall or contrariwise), it will fail with a message like "platform not supported".

The trouble is, I can't always grant that the required VM is present at the time of uninstallation... E.g., my user is quite free to do following (assuming no Java was installed before):
1. Install 32-bit Java.
2. Install my software (this would unpack iawin32.dll)
3. Uninstall 32-bit Java, install 64-bit instead.
4. Attempt to uninstall my software.
This would fail as we're missing iawin64_x64.dll...

And I must add, it's not a fantastic scenario; my QA files me bugs about this now and then, so that it's quite possible with customer's setup too 😞

I can see that the problem is ultimately solved if I have both iawin32.dll and iawin64_x64.dll copied [manually] in the install dir; however how do I achieve it programmatically?...

So the actual question runs like this: is there any feasible way to get IA copy both iawin32.dll and iawin64_x64.dll without manually adding them to my IA project? Like some secret setting in IA project, or whatever...

Thanks in advance,
PS. Oh, and I can also see that IA home additionally has yet another DLL: iawin64.dll. Anyone knows what's this guy for?
PPS. Well, there is an [ugly] workaround: configure the project to "use 64-bit only or die" or "use 32-bit only or die". Alas, that's not a solution for me for certain reasons (OK if I skip details why exactly?) 😞

Have a look to this post at least:

At build time, get the 64-bit dll you need from: C:\Program Files\.....\InstallAnywhere \resource\nativetools\windows

In Install tab of InstallAnywhere UI, select the "uninstall" folder and put this "iawin64_x64.dll" into subfolder called "resource". Add the correct rules for this action to match your project needs.

Yeah, that's exactly the thread I googled up and the solution I've taken.
Just a bit of caveat: to avoid 64-bit DLL being deployed on Win32 it makes sense to mark these files in project as targeted for 64-bit architecture only. And to avoid your installer raising "Overwrite" dialog, set the "Overwrite" flag for these files to "Skip".

Still, looks kludgy like hell..

It is easy to reproduce the error.

Project--> Jave --> do not select the "Bundled Virtual Machine"

Build--> Build Targets --> Windows with VM.

build the project and install it to the windows machine, when uninstall it, will have the same error
