Error: "Could not convert variant of type (Null) into type (OleStr)" (4326443)

Received the error: "Could not convert variant of type (Null) into type (OleStr)" when performing one of the following actions:

- Connection
- Creating profile
- Renaming profile

CAUSE 1:
Application is unable to locate the connection profile file

CAUSE 2:
Windows client does not have the 'C:\Documents and Settings\All Users\Application Data\Shared\Profiles' directory

CAUSE 3:
The connection profile file(s) is/are invalid or corrupt.

CAUSE 4:
Product defect

WORKAROUND 1:

Modify the connection profile directory appropriately through the Connection Manager.
1. Launch Performance Analysis
2. At the Connection Manager, click on the Tools | Options, then set a valid connection profile directory to the path 'C:\Documents and Settings\All Users\Application Data\Shared\Profiles' directory.

Please note:
Prior to setting the connection profile directory , open Windows Explorer and back up your Profiles directory

WORKAROUND 2:

1. Shutdown Quest Central / Performance Analysis
2. Back up the contents of the profiles directory (C:\Documents and Settings\All Users\Application Data\Quest Software\Shared\Profiles)
3. Delete all files and folders from the Profiles directory
4. Restart Quest Central / Performance Analysis .

Please note:
It will be necessary to re-enter logon information

WORKAROUND 3:

1. Search through all the profiles folders looking for any folder that has a profile.xml that is 0 bytes in size.
2. Delete any of these corrupted folders that contain the 0 byte profile.xml.
3. Once you have removed all corrupted directories you need to recreate any profiles that you had to delete.

Additional information:
In versions prior to Performance Analysis 6.1.113, the connection profile is predefined to store in the 'C:\Documents and Settings\All Users\Application Data\Shared\Profiles'

This error may occur in Quest Central.

WORKAROUND 4:
Use this workaround if a profile with the name "New" is created instead of the selected/specified name.

1. Close Performance Analysis client.
2. Go to the connection profile directory 'C:\Documents and Settings\All Users\Application Data\Quest Software\Shared\Profiles\New\',
3. Open profile.xml file then find and replace "New" with the "<Instance Name>" and then save the file.
4. Rename the directory from 'C:\Documents and Settings\All Users\Application Data\Quest Software\Shared\Profiles\New\'
to
'C:\Documents and Settings\All Users\Application Data\Quest Software\Shared\Profiles\<Instance Name>\ '
5. Open Performance Analysis client. The profile name will then be displayed correctly.

STATUS:

Waiting for fix in a future release of Performance Analysis Oracle and Performance Analysis SQL Server.
