Installation help.

I already have Rasayan Draw. Which download do I need? +

Use the same package above. Setup detects a supported existing installation and offers an update. Save your open work and close Draw and Office applications first. Keep your current licence and drawing files.

What if an Office application is running in the background? +

Save your documents and close the applications listed by Setup. Review the installer’s close-applications prompt carefully before proceeding; force-closing an application can discard unsaved work.

Can I use it without an internet connection? +

Drawing and scientific calculations run locally. For file-based activation, export your device request, send it to Rasayan, then import the signed activation file returned for that device. Account activation uses a network connection and may synchronize the licence when connected.

Why does Windows show an installation warning? +

The current release does not have an Authenticode publisher signature. Your organization’s policy or Windows security settings may block it. Do not disable security protections. Contact your IT administrator or Rasayan support for an approved installation route.
