I cannot drag tools and databases from the ribbon to the design view

Have you created a new project? File > New project

I get an error that the 'model' object is not defined in the database

That tends to happen when you accidentally switched your input and output in the Run SpineOpt tool.

Solver throws error `Name too long`

Variables and constraints names in SpineOpt sometimes can be longer than the maximum name length the solvers allow. If you get this error, we recommend using the solver parameters to run it ingnoring the names. For instance, Gurobi has the parameter IgnoreNames which allows to run without the names but returning the solution with the original names in the model.

To setup the solver parameters you can look at the How-to section guide change the solver and define its parameters.

SpineOpt and SpineInterface are out of sync

Some of the development of SpineOpt depends on the development of SpineInterface and vice versa. At some points in time that can create an incompatibility between the two.

You could get an error like:

ERROR: LoadError: MethodError: no method matching MathOptInterface.EqualTo(::SpineInterface.Map{Symbol, SpineInterface.TimeSeries{Float64}})
Closest candidates are:
MathOptInterface.EqualTo(::T) where T\<:Number at C:\\Users\\prokjt.julia\\packages\\MathOptInterface\\vwZYM\\src\\sets.jl:223

It might just be a matter of time before the projects are updated. In the meanwhile you can check the issues whether someone has already reported the out-of-sync issue or otherwise create the issue yourself.

You can also try another version from the installation options.

Julia 1.5 UUID ERROR

Using Julia 1.5.3 on Windows, installation fails with one of the following messages (or similar):

julia>  pkg"add SpineOpt"

The solution is to update the julia registry and install SpineOpt again.

Reset your Julia General registry. Copy/paste the following in the julia prompt:

using Pkg
rm(joinpath(DEPOT_PATH[1], "registries", "General"); force=true, recursive=true)
withenv("JULIA_PKG_SERVER"=>"") do
    pkg"registry add"
end

Try to install SpineOpt again.

Windows 7

On Windows 7, installation fails with the following message (or similar):

julia>  pkg"add SpineOpt"

The solution:

Install .NET 4.5 from here: https://www.microsoft.com/en-US/download/details.aspx?id=30653.
Install Windows management framework 3 or later, from here https://docs.microsoft.com/en-us/powershell/scripting/windows-powershell/wmf/overview?view=powershell-7.1.
Try to install SpineOpt again.
