"Pro’s and Con’s" of installing LoadRunner 11.0 on 64-bit Operating System
– LR Analysis will have bigger memory limit on Win64, so working on large graphs are easier.
– LR is a 32 bit application currently. Support for 64-bit OS is in the plans for a future release — but the date has not been announced.
– There are no direct benefits of running a 32-bit application on a 64-bit OS.
– Due to LR 11’s 32 bit design, it should be possible to record 32-bit applications on a 64 bit Windows OS, but not 64 bit applications. In general, recording support on Windows 64-bit OS is not tested or supported currently.
Note: Limited testing has been done in this area, other than for the OSs mentioned in the readme.htm that comes with LR11 in the product distribution.
