We have been running 5.2.3 for quite a while and have a test suite that takes around 40 minutes to run. After upgrading to 6.0 the suite takes several hours, and so we have had to abandon our upgrade plans for the moment.
We would attempt an upgrade to 5.4.5 in the mean time, but can't find a link to the 64bit version. Any way I can get a link to old builds of Isolator?
