Hi there,

I'm trying to deploy a Bundle from Eclipse Neon for x64 architectures.
The project comes out from a x86 architecture setup and recall a .NET component via OLE.

I set up all the Environment: Java x64, dlls recompiled and registered for x64, updated osgi and swt libraries....

The problem is that once I run the product (from Eclipse), the main GUI of my application partially loads, but I got the following message:

"org.eclipse.swt.SWTException: Failed to create Ole Client. result= -2147221164
    at org.eclipse.swt.ole.win32.OLE.error(
    at org.eclipse.swt.ole.win32.OleClientSite.<init>(
    at ....."

It seems the OLE component fails to run. To try solving this, I registered the dll (developed in VS) into ActiveX using RegAsm.exe (\windows\Microsoft.NET\ folder), but this didn't solve the problem.

Every help will be gratefully accepted.

Thank you.

I am also getting similar issue when I am executing below code:-

try {
frame = new OleFrame(shell, SWT.NONE);
clientSite = new OleClientSite(frame, SWT.NONE, "Passport.system");
