View source for Faq easy way to switch from one version of PLS Toolbox to another

===Issue:===

Can you describe an easy way to switch from one version of PLS_Toolbox to another?

===Possible Solutions:===

The easiest way to switch between versions (or separate installations) of PLS_Toolbox is to use the <code>evriinstall</code> script: 

#Make the main folder of the version you want to install the Current Directory in Matlab. 
#Close all GUIs and clear all objects using the following commands at the Matlab command line ('''WARNING: This will clear all variables in the Matlab Workspace'''): 
 >> close all force
 >> clear classes
<ol start="3">
<li>Run evriinstall from the command line with the 'silent' switch to avoid the installation splash screen:</li>
</ol>
 >> evriinstall silent
<ol start="4">
<li>Enter your license code if prompted. I some cases your existing license code will work so you may not be prompted to enter a new one.</li>
</ol>

To switch back simply follow these steps for the folder/version you want to use. The <code>evriinstall</code> function takes care of removing old versions from the Matlab path. 

You may find that DataSet objects you create in a newer version may not be backwards compatible to older versions of PLS_Toolbox. In this case, you will see a warning "Loaded dataset object newer than present constructor.". To correct this, [[Faq_make_DataSet_backwards_compatible | see our FAQ item on this issue]].
