Notes about the LRR file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The LRR file type is primarily associated with 'Mercury LoadRunner' by Mercury Interactive Corporation. Opening this file gives access to an Access database with results of a specific performance/load/stress-test.
