I have tried Wavelab LE on three computers, my main workstation, a laptop and a virtual machine.
I have installed WaveLab LE 9 successfully on all three successfully, using the autoupdate on one and using the standard WaveLab_LE_9.0.25_Installer the anothers. In other words I have tested versions 9.0.25 and 9.0.30.
All three machines exhibit the exact same behaviour, after starting the WaveLabLE9_0_64.exe process, and either being prompted to continue or register, the process sits there running and continually eating up more and more RAM with no UI appearing or anything else apparent happening. Registering the product successfully makes no difference.
After the process launches, it swallows up as much as the system can allocate, and it then crashes.
I am very angry that a fresh install on a totally fresh machine (in the case of the VM) does not work out of the box. As a paying customer who is laughed at by peers for choosing to pay for a copy of WaveLab LE with limited functionality compared to their illegal pirated copies, that I am left with nothing to show for my money, except for having to waste my free time trying to get support from Steinberg.
I am totally dismayed at clear the lack of QA by Steinberg.
