Fix: make ownCloud installer display in English language

OwnCloud is an interesting solution for setting up a file sharing cloud for a group of people.

However,one issue I’ve found with its Windows desktop client’s current version (which looks clean of any viruses since I always check first) is that if your Windows 10 is configured with a preferred language that the desktop client’s installer doesn’t have localization support for, then it doesn’t show up in English as you’d expect, but in Czech or someother language that most of us don’t know how to read.

So I tried running it’s MSI installer (ownCloud-2.6.1.13407.13049.msi) with –? parameter from the command-line and the /g languageCode parameter mentioned there looked promising, but trying /g en for English didn’t work. I guessed it needed some specific language code number (and not double-letter language code like en for English), since the help text was mentioning to see Windows Installer SDK for more help.

After a quick search I found an article that suggested passing the parameter Productlanguage=1033 to an msi installer on the command-line for it to ALWAYS show in English. And indeed it worked.

To open a command window one can click the Search icon on the windows taskbar and type CMD then press ENTER.

Then they can drag-drop the .MSI file of ownCloud installer onto the black command-line window that opens up and type an extra space char and then Productlanguage=1033 before pressing ENTER to launch the ownCloud installer in English. After that they can close the command-line window at anytime.

Since many users may be uncomfortable with such instructions, one could provide an msiEnglish.bat file that just contains

%1 Productlanguage=1033

User could drag-drop the .msi they want onto that msiEnglish.bat file and it would run the msi installer being displayed in English language, irrespective of any preferred language settings at the Windows operating system.

Of course the best thing would be if ownCloud fixed their desktop client installer to fallback to the Engish language (set it as default) if it can’t find localization strings for the currently prefered language of the user. Have filed an issue at https://github.com/owncloud/client/issues/7825
