Unable to open Toad, please verify that it is correctly installed (4239577)

Launching Toad via Performance Analysis either by killing a session or through Advisories, throw the following error:

"Unable to open Toad, please verify that it is correctly installed"

If the client machine has multiple copies of Toad (e.g. 9.7.2, 10.1, 10.5.1), it does however launches version 10.1 but not 10.5.1.

Old Quest branded Toad versions:

CAUSE 1

PAO GUI is looking for the Toad installation path in this registry key - HKEY_LOCAL_MACHINE\SOFTWARE\Quest Software\TOAD.  Version 10.5.x does not use this registry anymore.

CAUSE 2

PASS GUI is looking from HKEY_CURRENT_USER\Software\Quest Software\Toad for SQL Server.  This normally happens if the user launching Toad from PA GUI was not the one who installed the Toad software.

For Dell branded Toad Versions:

The PA client is under limited support and this broken feature will not be fixed.

WORKAROUND 

Please use the "Copy to Clipboard" button the pop up window which appears when you click on "Kill Session". Now open Toad to run the copied statement.

Old Quest branded Toad versions:

WORKAROUND 1

If only Toad for Oracle version 10.5.1 is installed, create a registry key as follows:

[HKEY_LOCAL_MACHINE\SOFTWARE\Quest Software\TOAD]

Create the following String values:

CLIENT = C:\Program Files\Quest Software\Toad for Oracle 10.5
SERVER = C:\Program Files\Quest Software\Toad for Oracle 10.5

WORKAROUND 2

If multiple Toad installations are installed and you want to launch version 10.5.1 then modify the CLIENT and SERVER string values under HKEY_LOCAL_MACHINE\SOFTWARE\Quest Software\TOAD to reflect the installation folder of 10.5.1

WORKAROUND 3

For Performance Analysis for SQL Server launching Toad for SQL Server:

1. Login to the machine as the user having issues
2. Open the registry editor (regedit).  Please be careful in editing the registry.
3. Create 2 Registry keys within the HKEY_CURRENT_USER:
   
   HKEY_CURRENT_USER\Software\Quest Software\Toad for SQL Server
   
   Under this create a string value INSTALLDIR and data of "C:\Program Files (x86)\Quest Software\Toad for SQL Server 5.8.0\" without the quotes or whichever you installed Toad.
   
   HKEY_CURRENT_USER\Software\Quest Software\Toad for SQL Server\5.8
   
   Under this create the following string values:
   Edition (Toad for SQL Server Xpert)
   INSTALLDIR (C:\Program Files (x86)\Quest Software\Toad for SQL Server 5.8.0\)
   Licensed By (Toad for SQL Server)
