After installing the PS wizard I am asked for the repo containing the powershell command. I tried looking for the documentation the wizard says is in the default studio document path. I cannot find the document it is referencing.
PS Wizard is looking to the Run PowerShell Script operation that should be available in your repository.
The repositories you may use:
1. Public repository, ussually located at %OO_HOME%\Central\rcrepo. As soon as you install the OO Content Pack you'll find in your public repo all the content (including PowerShell one)
2. A repository where you need to ensure (in Studio, by pulling from the Public Repo or by exporting a micro-repository)
that Run PowerShell Script operation is present
2.1 If you pulled in your Studio Local Repository from the Public Repository then you can point the PS Wizard to %OO_HOME%\Studio\studiorepo location
2.2. If you exported a micro-repository containing the PS operation you may point the PS Wizard to the folder where you've exported.
Hope it helps,
