Overview
During installation, the Single-User Edition option may be unavailable:

Cause
The installation is being performed on a Windows Server operating system. Under the QQube Licensing Agreement, the QQube Single-User Edition cannot be installed on a server operating system.
Installation requirement
The QQube Single-User Edition can be installed only on a workstation or laptop.
Resolution
Choose the installation method that matches your environment:
- Workstation or laptop: Install the QQube Single-User Edition locally.
- Server, Remote Desktop, or hosted environment: Use the QQube Multi-User Edition.
Single-User Operating Limitations
The Intuit Software Development Kit controls how QQube communicates with QuickBooks. During a Single-User synchronization, these restrictions apply:
- You cannot work in QuickBooks.
- You cannot open a second instance of QuickBooks.
- Other applications may respond more slowly because the Intuit SDK can use substantial processor resources.
- The QuickBooks login must have sufficient permissions for all required data to be extracted.
Multiple QuickBooks Company Files
When a Single-User installation synchronizes multiple company files:
- QuickBooks must be left open with no company file selected.
- The Windows user running the synchronization must remain logged in.
- QuickBooks must be in multi-user mode before the scheduled synchronization begins.
Why Multi-User Is Better for Server Environments
The QQube Multi-User Edition uses a dedicated Windows server user for synchronization. That user remains logged in with QuickBooks open to no company file.
Other users can continue working in QuickBooks under their own Windows sessions while QQube synchronizes one or more company files.

Limited Exception
Single-practitioner hosted environment
A single practitioner or CPA using one copy of QuickBooks Accountant in a hosted environment may request an installation workaround by contacting admin@clearify.com.
The Single-User operating limitations described above still apply.
