Hi Stefanie Waldtmann,

Have you tried uninstalling and reinstalling Studio? If not, I would try it as it may smooth out whatever was changed by the Windows Update.

It also might be worth re-running Windows Update to see if maybe it will reinstall correctly, in case the update process was somehow interrupted and corrupted...

Also, I ran a Google search on this error and the only one that seemed to give a solution that was specifically applicable to Windows rather than another piece of 3rd part software was here:

wikifixes.com/.../

It gives an explanation of the 0x80010001 error and offers the trial version of a downloadable tool to scan for errors in your registry and fix them. It looks pretty genuine...

I have no idea if that will fix your problem but reading the content may help someone looking at this thread to think of another solution to your problem.

All the best
Alison

Hi Stefanie,

I'm sorry none of my suggestions were solutions. Is it possible that your antivirus perceived the download as malware because of its behaviour, but that it wasn't? If so you probably need to add it to your antivirus exceptions list but if you're in any way suspicious of it, then of course don't.

Can I suggest that instead you download CCleaner here:

CCleaner

Click on the green 'Download latest version' button, not on any other enticingly-coloured download button (adverts for other software).
Once downloaded, you can use this tool to clean up your registry after all the changes that have gone on with the last 2 days' updates.

Whether you do the above or not, you can get help quickly from SDL here:
