their response is now stored in the INI file to prevent the user being asked again.
- Resolved a backwards compatibility issue with old versions of CMNet.exe when a Secure Data Area was specified.
||15 Apr 2009
A protected program now searches for its protection-related files in the same places as before, but in a different order:
- Path variable in .cm.ini file in same directory as the protected program.
- Path set by CM_SetPath() API call (now deprecated but supported for existing installs).
- The protected program's directory.
- A 'cm' sub-folder of the protected program's directory.
- The path %APPDATA%\<DID>\<Product Code>\cm
- The path %ALLUSERSPROFILE%\<DID>\<Product Code>\cm
Behaviour of the ActivationByProductKey and Trial variables in the .cm.ini file has been modified. Previously,
if they were set to 'Manual', the protected program would try to use the internet to get the 'manual' security tolerance settings.
Now, the protected program will only allow activation by manual activation code.
Improved clock tampering detection and handling -
if an installation does not require the system clock to be accurate (i.e. no expiry date or periodic web access required),
the user may change their clock without affecting the protected program.
- CMInstall records install date in .cm.log file.
- CMInstall no longer allows /C (current user) command-line option under Vista.
- Improved error reporting.
- Improved encryption of the Secure Data Area.

Invalid data no longer saved if the user enters an invalid activation code too many times, or if the user
cancels part of the way through a manual activation or update.
- A protected program no longer gives 'system clock gone back' error after automatically correcting the system clock.
- CM_SDA_Read() API function - 'flags' parameter now works correctly for network installations.

- SDA is now available for Trials.
- For a network install, SDA functions now read/write the server's .cm file instead of the local copy.
- Changes to the SDA on the web site now get downloaded to the installation when they next access the web site.
- Can now add/change/delete SDA directly from another web server by, for example, an online order system.

- Some Custom Dialogs were not working correctly.
- CM_EndNetworkUser API call now works ok.
||30 Apr 2008
- The Shell method is now compatible with a much wider range of executables, particularly those developed with MS Visual Studio.
- .cm.ini file variables changed. Some developers found the NormalInternetActivationAllowed,
ManualActivationAllowed and TrialAllowed variables confusing; these have been replaced by:
ActivationByProductKey = Internet|Manual|Either|Neither
Trial = Internet|Manual|Either|Neither
This is less ambiguous and more flexible, permitting any combination of Internet and/or Manual activation of Normal and/or Trial installations.
Further details can be found in the user manual (CopyMinder SDK 3.3 and later).
The previous variables remain for backwards compatibility but are no longer documented.

- CMInstall now supports single-user and all-user installations. All-user installations to
Program Files used to cause problems on some Vista installations (typically error 602, 604 or 606).
- Improved CMInstall: /Q and /V switches can be used to control the display of
messages (defaults to only display errors). /K switch can be used to keep any existing
.cm file in the destination path rather than overwriting it (useful if the user re-installs or updates your software).
- CMInstall now defaults to English (instead of French) for unsupported languages.
- Bug fix: now supports the temporary addition of a PCMCIA network card.

- Added increased flexibility in deciding what release to upgrade users to.
||20 Oct 2006
Bug fix upgrades to newer releases of the .cm file occasionally timed out on slow or poor internet connections giving error 566/12.
