The portable version of DAX Studio is distributed as a single zip file.
To run the portable version you just need to unzip the zip file into a folder and double-click on the DaxStudio.exe file.
When running the portable version any settings, logs and query history will be saved in sub-folders under the folder holding DAX Studio so you can copy/paste this folder between machines or store it on a USB drive.
When using the portable release DaxStudio.exe saves users settings to the local folder . Therefore the portable install should never be copied into the
program files folder.
The Excel add-in is not available when using the portable install as the add-in needs to be installed in order to be registered with Excel.
The Power BI Desktop External Tools integration is not available when using the portable install as the external tools registration file needs to be installed in a specific folder under the 'Program Files' folder order to be registered with Power BI Desktop. (the All Users install option should be used if you require Power BI Desktop integration)
