Issue with SWAT+ Toolbox (v3.2) Compatibility with QSWAT+ 3.0.3 and SWAT+ Editor 3.0.8

[Chandu Palakuri]

Dear SWAT+ Support Team,

Good evening.

My name is Chandu Palakuri, and I am currently working on a SWAT+ project for water availability assessment. I recently installed the SWAT+ package with the following components:

• QSWAT+ Interface: 3.0.3
• SWAT+ Editor: 3.0.8 (rev. 61.0.1)
• SWAT+ Toolbox: 3.2 (installed instead of 2.4 included in package)

While opening my project in the SWAT+ Toolbox, I am encountering an error. I suspect this issue may be due to a version mismatch between the Toolbox (v3.2) and the QSWAT+/Editor versions.

I would like your guidance on the following:

1. Is SWAT+ Toolbox v3.2 compatible with QSWAT+ 3.0.3 and SWAT+ Editor 3.0.8?
2. Should I downgrade the Toolbox to v2.4 (as provided in the installation package)?
3. Are there any recommended version combinations to ensure smooth workflow between QSWAT+, Editor, and Toolbox?
4. Kindly help me understand how to resolve this error and successfully open my project in the Toolbox.

I have attached the error message screenshot for your reference.

Thank you very much for your support.

Kind regards,
Chandu Palakuri
