Upgrade StorageZotero installer should put the architecture in Windows' Control Panel/Add or Remove Programs
Windows' list of installed programs under Control Panel/Settings -> Add or Remove Programs lists all installed applications including their version string. However, Zotero uses the same PackageName for both 32 and 64 bit applications.
This confuses Windows' package management: if somebody has the 64-bit version installed and wants to update to a new version, it might - instead of updating - just install the 32-bit version alongside.
Solution would be to change the PackageName string depending on the architecture. E.g. instead of simple "Zotero" it should be "Zotero (32-bit)" and "Zotero (64-bit)".
