Hi Dorota Miklasinska 

Please try to install Studio 2015 manually: https://gateway.sdl.com/apex/communityknowledge?articleName=000001136

If it doesn`t work, try the solution from this article: https://gateway.sdl.com/apex/communityknowledge?articleName=000001400

Thank you,

Sorin

Hi Sorin,

Thanks so much for getting back to me with these suggestions. The manual install did not work but one of the suggestions in the article did work.

Unfortunately, I cannot activate my licence for some reason, either online or offline. I am not sure what to do, in my SDL account it seems that the licence is in use even though it has been deactivated from ages and that I am unable to log into the Studio as it is asking me to activate the licence. Screenshot of the error attached. Would be great to get this sorted out so help much appreciated.

I actually deactivated my licence offline and then reset the licence and get an offline activation code (nothing worked online).
