Hi

I'm sometimes having problems starting IE, it happens maybe 1/200 times but it's quite annoying.

Is this a known issue? or is there something i can do to prevent this from happening, from what i can see it's Telerik that fails to detect the browser or something like that.

Info:
We are running a test suite of 50 tests multiple times a day and i see this maybe once or twice a day.


Error message:
Initialization method Iit.TradingFloor.TestWebUI.ErrorPageTests.TopTestInitialize threw exception. System.ApplicationException: System.ApplicationException: Exception thrown attempting to launch Internet Explorer. Please make sure Internet Explorer is properly installed and you are able to launch it. ---> System.TimeoutException: Wait for condition has timed out.

I haven't found a solution to this issue.

I think I'm going to just wrap it in a try - catch even though that's not really a good solution.

Hello Martin,

This is definitely an environment-specific issue and it will be tough to nail down exactly what is causing the problem. Here are some other things to check:

  • Windows Updates - We've seen rolling back certain updates remedies issues similar to this.
  • IE Toolbars - If you've ruled out problematic Add-ons, there may be a toolbar interfering.
  • Anti-Virus - Do you run Anti-Virus software or your machine? Did it recently update? Does it plug in to the browser?

In order to launch IE without add-ons go to Windows Start Button->All Programs->Accessories->System Tools->Internet Explorer (No Add-ons).

Hope this will help.

I think your right, it also doesn't appear to happen on our VMs runnng a server version.

I think for now i will see if the try catch workaround works. If it does then Ill leave it at that and if it doesn't ill come back to you and we can spend more time investigatin.

For now I don't think it's worth using alot more time on.
