Thank mrsharegood, but you should have included more detailed instructions about Infovox.
I managed to install it after some fiddling in Virtualbox.
In order to install Infovox as a 30+ day trial, one must do the following:
1) Install Infovox with all the desired voices.
2) Open the license manager.
3) Activate the built in 30 day trial license.
Now proceed to the site key generation. There must still be time left of the trial for the following procedure to work.
4) Read/copy paste the site code from the license manager.
5) Start ckgen.exe and tab down to the site code field, and ppaste the site code you retrieved from the license manager.
6) Tab down to the checkbox Add to license and check it.
7) Tab down to the radio button Limits and select Days In the Days field, enter a high value i.e 2000 days.
8) Tab further to the Generate button and generate a site key.
9) Copy the generated key and enter it in the license manager.
If these steps fail:
Uninstall Infovox 230 completely.
Stop the service Crypkey license.
In Windows XP, enter this command from the command prompt:
net stop "Crypkey License"
Delete the files ckldrv.sys and crypserv.exe in the root folder (c:\).
Delete the root folder infovox.lic.
Delete the file(s) esnecil.* in c:\windows\system32.
Also delete the following files, if present, in c:\windows (or the folder where Windows is installed).
C:\WINDOWS\Setup_ck.exe
C:\WINDOWS\Setup_ck.dll
C:\WINDOWS\Ckrfresh.exe
C:\WINDOWS\Ckconfig.exe
C:\WINDOWS\system32\Crypserv.exe
C:\WINDOWS\system32\Ckldrv.sys
C:\WINDOWS\Crypkey.ini
C:\WINDOWS\CKSNNT.flg
Crypkey records trial info in registry under:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]
You will find two values under that key:
"CurrentBuildId "
"SystemType "
These are created by crypkey. They can be deleted.
Restart your computer (though that may not always be mnecessary).
Install Infovox 230 again and continue with step 2.
Thanks again Mrsharegood for a good share.
I apologize for my English.
