Troubleshoot VM problems 编辑

Citrix provides two forms of support:

• Free, self-help support on the Citrix website
• Paid-for Support Services, which you can purchase from the Support Site.

With Citrix Technical Support, you can open a Support Case online or contact the support center by phone if you experience technical difficulties.

The Citrix Support site hosts several resources that might be helpful to you if you experience unusual behavior, crashes, or other problems. Resources include: Support Forums, Knowledge Base articles, and product documentation.
