Thg 5.5.2 x64 for Windows tries to write log into "Program Files"
Workbench can not be opened. Attempt to start it always results in the following error message:
The logfile 'C:\Program Files\TortoiseHg\thgw.exe.log' could not be opened: [Errno 13] Permission denied: 'C:\\Program Files\\TortoiseHg\\thgw.exe.log'
There is no such problem in 5.5.1.
