Export to Flash Causes UE

[Kris C]

Hello,

While testing, we came across an unhandled exception when trying to export to "Flex (Flash") format.

Create a graph with any data
Open Options Dialog
Export Tab
Select "as Flex (Flash)"

Get the following exception:
System.UnauthorizedAccessException: Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Steema Software\TeeChart.NET' is denied.

We are NOT running as administrator and this is on the end-user machine so we cannot "install" TeeChart. it appears some additional defensive logic is needed here.

As with previous bug fixes, providing the diff of the fix should be enough to apply the necessary changes.

Hello Kris,

We are NOT running as administrator and this is on the end-user machine so we cannot "install" TeeChart. it appears some additional defensive logic is needed here.

Yes, I agree, although your app running on the client machine could ask for UAC administrator permissions.

As with previous bug fixes, providing the diff of the fix should be enough to apply the necessary changes.

I've attached the diff.
