Conflict access to temporary folder

Lorenzo,

TestComplete uses the Temp folder to save data during the recording. Perhaps, there is a conflict between your application and the Test Visualizer functionality as it saves the images to the Temp\TmpN folder (where N is 1, 2, 3, etc.)

To avoid the problem, I'd suggest that you disable Test Visualizer, or try modifying your test so that it does not use this folder.

Also, I'd suggest that you examine your application as locking the Temp folder and its subfolders does not seem to be a good solution, because this may cause problems with other applications.
