How to delete corrupted Instance DB?

Hello All,

I need some advices/ ideas how to delete corrupted Instance DB from TIA portal (V17).
I have a instance DB that somehow got corrupted (probably due to incorrect assignment of Prodiag FB).
What I tried so far is:

- compile/ rebuild all,
- check integrity test,
- save the complete project under different name
- Copy/pase corrupted block to different folders ETC.
- tried to recreate assigned prodiag FB with name the corrupted DB expects

It is always crashing....



The same happens (TIA crashes) whenever I'll try to correct prodiag FB under 'attributes' tab in properties of corrputed IDB.



Any clever ideas how to delete it?

Hi!

I recommend you to download the .dr file generated in the crash, by clicking on save as. And create a Support Request, attaching the file, so that the technicians can analyze the specific error that occurs in this case.
