The current COGPACK Version is 9.42.
Some anti virus programs report a virus within the program AnaPerm.exe. This is a false diagnosis. During installation of COGPACK you have to disable those anti virus software. AnaPerm.exe is not required for regular use and can be deleted on the HDD after installation.
We contacted those distributors of anti virus software and some have already corrected their virus signature files.
Changing formats starting with version 9.10. Tests on Windows 10 showed proper functioning.
There were some problems with the exercises "On-the-road", "Ball", "Piece-work" and "GuessWords: running letters". Starting with version 8.60 there are newer versions of those exercises on CD2. Users from older COGPACK versions can request the newer exercise programs.
