Error starting Cuba Studio SE 6.8

Installed Cuba Studio SE 6.8. When I start the studio I get following error -


Tried without proxy same issue.

Could you bring more details of your actions?
Have you installed Studio SE “for all users” or “only for current user”?
Why have you installed Studio on the D: drive?
Has the logged in user rights to read the folder, which is mentioned in the exception?
Could you also check, may be your Antivirus software has blocked some of the files?

Try to install Studio 6.9 SE or Browser Edition. Is it work OK on your system?

Thanks. Antivirus software was blocking this.
