Question / Problem
TreeSize takes a long time to start when it is virtualized using App-V. What is the reason for this?
Answer / Solution
Our 3rd party library which manages our installation keys iterates the registry key HKEY_LOCAL_MACHINE\CLSID which takes magnitudes longer under App-V virtualization than on a normal system. A possible solution is described here: https://social.technet.microsoft.com/Forums/en-US/1648d88e-72bb-4bf9-92b3-4a803e431650/problem-to-sequence-treesize-professionnal?forum=mdopappv
We will replace the library that handles the installation in keys in TreeSize V8.0 so that this iteration will no longer take place.
