Hello! Have you updated from the client? If you keep failing to update after updating from the client, please update from our official website. If you are still having problems updating from the official website, please contact me and I will find alternative solutions for you.
hey thanks for the reply,
what do you mean about updating from the client? i couldn’t seem to reach welcome page due to the error window popping up, but i downloaded latest version from the official website if you referring that. And i’ve done that 3 times already
Hello, I think it may be that your antivirus or firewall is blocking some of the contents of the D5 installer. I will try to send you an installer directly via private message and you can try to install using this installer.
Hello, I have same problem, tried many times but couldn’t start it.
Hi mate,
Please try reinstalling with a different installation path. And disable VPN, antivirus, encryption and other non-using software before installing. What browser are you currently using to open the D5 website? Try another browser.
Hi there could you find the solution? i tried all but still ive same problem… Thx.
Hello, please try to uninstall the original D5 completely and then download a latest installer from our official website. Delete these folders with d5 prefix under your personal folder in C drive and reinstall it.
Also, please pay attention to your windows version and don’t use an too old version (please update your system to win 10 2ih2 or above)
