Installing

Q:
What would be a step by step to create a Lianja windows service?
A:
Method 1: .bat file calling app with lianjaruntime.exe –app appname Run as Windows Scheduled Task, set to run on startup, with highest permissions.
Method 2: srvany.exe — blog post by Calvin Hsai here: http://blogs.msdn.com/b/calvin_hsia/…13/282351.aspx


Q:
Do I have to uninstall then download/install the current version?
A:
I have always just installed over, without a problem.
Before you install the current version, you will want to delete all the rollback directories under c:\lianja. These are from prior installs, and slow down the installation process.
There is no harm in uninstalling first: all your files are left.


Q:
I have reinstalled “LianjaAPaaSDeveloper-1.5-windows-installer”. (Just ran the exe.)
No error message. Lianja App Center is OK, but get startup screen and Hang only for Lianja App Builder.
A:
I’ve seen the Home Windows 7 versions fail on various installs, fwiw. You should be using a Professional version.


Q:
if I have to install Lianja 3.0 on top of linja 2 and the upgrade is done automatically or I need to uninstall version 2 and install version 3.
How about the application we already developed in version 2? Should I re-compile it and re-deploy it with this new version?
A:
you can install over.

Q:
How to cleanup Lianja installation?
In my Lianja folder I’ve a lot o folder “rollbackBackupDirectory“, 10 GByte!
Then I’ve a lot of entry in my “programmi e funzionalità” (I do not know how is in english where you install/uninstall program in Windows).
Can I delete the rollbackBackupDirectory?
If I unistall the old version of Lianja from my control panel, is better to “deactivate” Lianja before the uninstall, then “activate” after?
A:
Yes you can just delete the rollback directories. That’s a windows “feature”.
In v1.3.1 these are no longer created.
If you install a new version you do not need to deactivate and activate.
Also, after uninstalling, if you go into your “programmi e funzionalità” (Programs and Features) and click to uninstall any old entries, it should prompt you to just remove them from the list.



Installing

Q: 
Fresh start, re-install
A: 
1. Backup any Apps, data or scripts that you have created and want to save (these are in C:\Lianja\Apps and C:\Lianja\data. Library scripts are in C:\Lianja\library)
2. Assuming you installed in the default location, files are installed here (Win64):
C:\Program Files (x86)\Lianja
and here:
C:\Lianja
So, delete these folders.



Should be fine to just install over the top as long as your existing installation is in the default C:\Lianja. If you installed on an alternative drive, unset or remove any environment variables you set up for the installer before running the new one. If you installed in an alternative directory I would deactivate, uninstall and start from clean.



Unpack your .lpk file from the Apps Workspace. Just click the ‘Install package’ button and it will open a file dialog to allow you to select your package.
