Toad For Oracle : base Edition Installation Error System.DllNotFoundException: Unable to load DLL 'C:\Users\mashrkp\AppData\Local\Temp\tmp5A10.tmp': Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

I am trying to Install Toad For Oracle 2017R2 Edition Installer(X86) and am getting the below mentioned error as soon as I click Next on the main screen.

I am having full access the required path (C:\Users\mashrkp\AppData\Local\Temp\tmp5A10.tmp) and can see various .txt files created by TOAD.

Can anyone help me with this?

Thanks in advance!!!

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Hello,

It sounds like the “Bundle” is the issue here, the GUI interface that holds the MSI files. Please try running the MSI files directly, located here: https://support.quest.com/toad-for-oracle/12.12/download-new-releases
