Hello,

Since 2026-09-05 around 19:00, my tools no longer work.

Anyone have any ideas?

I can’t reach anyone by phone at Invantive.

Which on-premises product is this?

On which operating system and exact version are you receiving this error message?

I am working with version 24.0 of Invantive Query Tool and 25 of Invantive Data Hub. I have just downloaded version 25.0 of Invantive Query Tool.

Invantive Query Tool is now at version 25, but I do not know how to install/copy the Invantive Data Hub software (in a zip → with many files and subfolders upon extraction) to the program directory.

Can you help me with that? I also don’t know which version it is, I think it’s 25, because in the download folder it says this: Invantive Data Hub-win-x64-net10.0-windows-26.0.173

I don’t understand the question regarding which XML I use.

I am working with Win 11 Pro version 25H2.

The advice is to first upgrade to release 26.

Releases 24 and 25 in combination with Exact Online have reportedly not been compatible since approximately last May due to changes in the Exact Online identification protocol.

When using release 26, you also need to use the Invantive Credentials Server for Exact Online.

If you need assistance with this, it is advisable to schedule a short consultation via the option in the chat window.

Okay, you mention using a different connection, no idea how I should / can do that.

How do I schedule a consultation?
