Re: why are vdfx double the size than vdf files?

VDFX stores double precision numbers, VDF only stores single.

And no, it cannot be switched back to VDF files.

If size is a problem, you can use a savelist to cut down the amount of data you save.

Re: Specify sheet for MENU>VDF2XLS?

You cannot specify the sheet name. The sheet name will be the same as the runname (or what you are exporting to).

You could write some simple VBA in Excel to rename the sheet to whatever you need.

Re: Install error 'invalid signature' (8.2.1)

I am also having this issue with the invalid signature error when trying to install VensimPLE. The same happens if I try installing the model reader.

Re: 32-bit Excel cannot find 64-bit DLL

You cannot mix 32 and 64 bit DLLs. The only solution is to install Vensim 32 bit as well on your machine.

In the new Vensim 9.0, you can align controls. And you can get multi-line comments by using more than one.

Re: "Formatting..." message in View As Text mode

That is a "work in progress" message. It should disappear when the work has been done.

If you can email the model to us and let us know how to trigger the message, we should be able to fix it.

No, you cannot have different units within a single parameter. The only option is to convert to something common and back again if you need to.

Re: Optimization Constraints using non-constants, percentages summing to 1.0

You haven't uploaded the model so I cannot really say where you put them in.

Whatever you modify with the optimizer and need to sum to 1, insert this new structure after that.

Re: Optimization Constraints using non-constants, percentages summing to 1.0

You can use the inputs to calculate proportions instead and use those in your model. Something like input 1 = 10 input 2 = 20 input 3 = 30 total input = input 1 + input 2 + input 3 proportion input 1 = zidz ( input 1 , total input) proportion input 2 = zidz ( input 1 , total input) proportion input ...

ok, you haven't created the shortcut properly. This is a shortcut to the vensimdp.ini file, you need a shortcut to Vensim and pass in a different INI file.

Can you give me a screen shot of the new shortcut to launch Vensim and what you see when you use that shortcut?

Can you try putting a model in your "My Documents" folder and opening it from there?

Also, what operating system are you using?

2. What is the full path to the model you are opening? Do you have permissions to write to that particular folder?

Re: Error: Simulate button that does not work and MS3321 error

vensimdp.ini is the correct file to use to create the shortcut. The fact it exists suggests that is not the problem.

Can you take some screenshots and show us exactly what is happening?
