Question 4: How to make Psi+ portable under MS Windows?
Answer 4: To get Psi+ working in portable mode, you have several options:
Copy a folder PsiData from C:\Documents and Settings\%USERNAME% to C:\Program Files\Psi+ and start Psi+ via the script psi-plus-portable.bat
Convert psi-plus.exe to psi-plus-portable.exe using the script make-psi-plus-portable.bat
directly in the working Psi+ folder and then run psi-plus-portable.exe.
In the Downloads
page you'll find the latest Plugins Package and, not included in this package, the latest OTR Plugin.

As well as Vacuum IM, it's portable but not stealth
, for the same reasons.
