Nikon Coolscan V ED Connect

[noclue]

I have an issue connecting to the scanner.

First I got an Update of a Canon USB Scanner Driver. Afterwards I could no longer connect to my CoolScan.
I thought - no issue - just reinstall the Silverfast AI Studio. - I did so, but no improvement.
Then I removed Silverfast and reinstalled - no improvement.

Now I identified, that afer removal my License Info was gone and the Button for adding the License Info is "gray shadded".
Next Steps:
- Deinstalled Silverfast
- I cleaned up the registry.
- Installed Silverfast again
--> no improvement - I am not able to update the License Info. And therefore - I assume - I am not able to connect to the
Scanner.

Please could you give me a hint, how to remove the programm and re-enter the license - info? - Then I would be able to scan.

For verification I installed the Software on a different PC and everything works - but the PC is that slow, that I am not able to work there.

Thanks for your support.

Dear customer,

Do you have more than one SilverFast version installed?
In that case make sure you update all installed modules.
Also please only connect one scanner at a time.

kind regards,
