Unlike other applications there is currently no option to install SupportAssist x64 Old versions when it automatically pushed out new update version that does not work. 

There are reports of the new SupportAssist x64 version failing to undertake Hardware Scan Result (Manual). SupportAssist for PCs - Dell Community which then prevents system support's Diagnostic Full Test, etc. from being undertaken. 

Seemingly Dell wants SupportAssist to increase its role within many diagnostic features. However, becoming 100% reliant on the Dell SupportAssist application, imposes the strategic imperative that SupportAssist is fully functional all of the time. 

Is there going to be a fix/solution for users to install known SupportAssist version that works?
