Hello @all,

I´ve tried to install CT 4.20 on my Windows 7 Professional machine without success.
It seems for me, that some of the 7zip files are not fully decompressed.
As attachment the failure while the installation.
Any idea, I would happy about any advice.

try run cmd.exe with admin?

I look like this situation in two cases:

1) Initial script, setup.bat, runned from directory, that is not current directory. For example, this situation may be with double-clicking from Double Commander file manager.

2) Anti-viral software blocked the process of copying executables. Mostly: Avira Antivirus. It's paranoidal algoritm may detected viral code, if that no one.

I reported this problem to Avira and they promised a fix in the next engine update (cannot be fixed by their signature files).
