Problem description

Auto and manual upgrade of inSync Client initiated from the inSync Management Console.
Uninstall of inSync Client using Add/Remove programs.
Cause
Auto or manual upgrade of the inSync Client triggered from the inSync Management Console and uninstall using Add/Remove Programs fails if the client MSI was deployed using an MST file (answer file). Such installation can be upgraded or removed only using the MST file.

+code+Resolution
Druva Support will need the GUID of the installed inSync Client to provide you a custom script to address this issue.
Here is how you go about it:
Open the command prompt as an administrator and the this command to get the product GUID
wmic product where “name like ‘%%Druva inSync%%’” get Name,Version,IdentifyingNumber
Example with sample output:
C:\Windows\system32>wmic product where "name like '%%Druva inSync%%'" get Name,Version,IdentifyingNumber
IdentifyingNumber Name Version {7534B0B0-7CA2-4040-A4F1-7ED4FF70C356} Druva inSync 6.2.0 6.2.0.0
This is a sample output and may vary based on the inSync Client version installed on your environment.
Provide the product GUID (value under IdentifyingNumber) to Druva Support. You will get a customized script to further address this issue.
