You can apply (run) the attached .REG file, which will change the language setting to English:
This is the only thing it will change.
You can open the .REG file with a text editor if you wish to confirm what will be changed (always recommended). After you execute the .reg file you will need to restart the NovaBACKUP client and the nsService.exe (NovaBACKUP Backup/Copy Engine Service) in Windows Services, otherwise the change won't apply to all aspects of the software.
⚠️ WARNING: After changing the NovaBACKUP client language you are required to manually restart the nsService.exe task (that is the Windows service named "NovaBACKUP Backup/Copy Engine Service") and then exit the NovaBACKUP client and run it again, otherwise the language change you just made will not properly apply to all areas of the client software until that is done. You could also restart the computer to accomplish that.
NOTE: See the end of this article for the .reg file attachment.
If you wish to modify your registry manually instead:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\NovaStor\NovaStor NovaBACKUP
Right click on LanguageID and click Modify…
Change Value data to: 40A (Hexidecimal Base)
Start NovaBACKUP client will be in Spanish language.
Change Value data to: 409 (Hexidecimal Base)
Start NovaBACKUP client will be in English language.
Additional Values:
NS_LANG_CHS = 804 (CHS - Chinese, simplified)
NS_LANG_CHT = 404 (CHT - Chinese, traditional)
NS_LANG_ENU = 409 (ENG - English)
NS_LANG_FRA = 40C (FRA - French)
NS_LANG_DEU = 407 (DEU - German)
NS_LANG_ITA = 410 (ITA - Italian)
NS_LANG_JPN = 411 (JPN - Japanese)
NS_LANG_KOR = 412 (KOR - Korean)
NS_LANG_POR = 416 (POR - Portuguese, Brazil)
NS_LANG_RUS = 419 (RUS - Russian)
NS_LANG_ESN = 40A (ESN - Spanish)
NS_LANG_TUR = 41F (TUR - Turkish)
Note: The attached "NSLanguageToEnglish.reg" English registry key .reg file, which you can download and execute on a system that already has the NovaBACKUP client installed on it to change the language to English system wide, contains a single HKEY_LOCAL_SYSTEM (system wide) LanguageId registry key that is set to the English language (409 hexadecimal base value). This registry key .reg file, after execution by an administrator user, will apply the change to the system and will affect all users. Keep in mind that re-installing the NovaBACKUP client software, in one of the first dialogs seen prior to choosing Typical or Custom install, will prompt you to choose the program language to set and in that case it will only apply the language to the HKEY_LOCAL_SYSTEM key (system wide). You can utilize the additional values in the chart above to create your own .reg file per language that you need, just by replacing the English 409 hexadecimal value in the .reg to another hexadecimal value from the above chart, and save the file with the name of the language if you want, with the .reg extension. You will 100% need to restart the nsService.exe (NovaBACKUP Backup/Copy Engine Service) in Windows Services after changing the language registry key, otherwise certain aspects of the software will still display in the prior old language, also keep in mind that changing the language like this will not make old logs be displayed in the new language, the old logs when viewed in LogViewer.exe will still be displayed in the language that the registry key was set to at the time that the backup or restore job ran.
