I'm running pgadmin 4 v2.1 on win10 64 bits, and it's installed under the Postgresql 10 folder in Program Files (which for me up to now indicated it was a 64-bit version, but I see now that it seems pgadmin only exist as a 32 bit app).
With regard to upgrading to 4.30, I can only find a 32 bits installation file and that wants to install under Program Files (x86). The documentation does not say anything about these issues.
Is this a deliberate change - should I uninstall the previous version under Program Files and then install 4 v3.0 under Program Files (x86)?
