What is the size of the performance result you are trying to open? If this is a large file you may be getting out of memory exceptions due to poor performance of the machine. The quickest way to solve the crash is to delete or move the performance results to another folder.
Another option if you are running a 64 bit machine is to set the LARGEADDRESSAWARE flag on the Test Studio executable file.
To do this requires that you have Visual Studio installed:
1. Open a Visual Studio command prompt (the standard command prompt won’t have the path set properly), with admin privileges
2. Enter “cd C:\Program Files (x86)\Telerik\Test Studio\Bin”
3. Enter “editbin /LARGEADDRESSAWARE Telerik.TestStudio.exe”
That should be it. To double check that it worked, you can (in the same command prompt) run:
dumpbin /headers Telerik.TestStudio.exe
You are looking for something ~12 lines down that says “Application can handle large (>2GB) addresses”
