The Advanced Diary journaling/diary program from CSoftLab stores its license information in the Windows registry at HKEY_CURRENT_USER\Software\CSoftLab\Advanced Diary. When you install the software, you will have a 30-day trial period and the LicenseCode and LicenseName keys will not have any values set. You can see the values using the Microsoft Windows registry editor regedit.exe.

If you need to view the license information, you can navigate to the HKEY_CURRENT_USER\Software\CSoftLab\Advanced Diary key in the registry using the registry editor or you can open a command prompt window and issue the following reg query commands.

C:\>reg query "HKCU\SOFTWARE\CSoftLab\Advanced Diary" /v LicenseName

HKEY_CURRENT_USER\SOFTWARE\CSoftLab\Advanced Diary
    LicenseName    REG_SZ    John Doe


C:\Users\Lisa>reg query "HKCU\SOFTWARE\CSoftLab\Advanced Diary" /v LicenseCode

HKEY_CURRENT_USER\SOFTWARE\CSoftLab\Advanced Diary
    LicenseCode    REG_SZ    VN37-H79K-28ZZ-XMMUMM9XX9


C:\>

You can extract the information from the registry by right-clicking on the Advanced Diary entry in the registry and choosing Export and then saving the information to a .reg registry file. That will save all of the registry information for Advanced Diary. You can then delete all but the lines that are like the ones below, if you only need the license entries in the registry.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\CSoftLab\Advanced Diary]
"LicenseName"="John Doe"
"LicenseCode"="VN37-H79K-28ZZ-XMMUMM9XX9"

You can then import the registry entries after installing Advanced Diary on another system. You can import them by opening the registry editor and choosing Registry and then Import Registry File.

Note: if you are transferring the registry keys to an installation of Advanced Diary running under Wine on a Linux system, you can run the registry editor provided by Wine by opening a terminal window and then setting the WINEPREFIX environment variable equal to whatever Wine prefix you have set, if you are using one other than the .wine one, and then running wine regedit. E.g.:

$ export WINEPREFIX="$HOME/.wine-advdiary"
$ wine regedit

If you have saved the registry values to a .reg file, e.g. file.reg, and want to import the values from that file from a command-line interface (CLI), open a command prompt window as an administrator and run reg import "C:\path\to\file.reg". Alternatively, use regedit /s "C:\path\to\file.reg" to import the file silently without a confirmation prompt. To import the registry values from a Windows system into the registry for an instance of Advanced Diary 9.0 running in a Wine prefix named .wine-advdiary on an Ubuntu Linux system, I used the commands below in a terminal window to import a .reg file named AdvancedDiary_LicenseInfo.reg.

$ export WINEPREFIX="$HOME/.wine-advdiary"$ wine regedit /s "$HOME/Documents/AdvancedDiary_LicenseInfo.reg"
$

After doing so, when I clicked on Help and chose About Advanced Diary, I saw it was registered.
